How to pass your practical driving test (tips etc)

The practical driving test is more about the safety aspect of your driving skills and abilities. It will first involve having your eyesight checked so that the examiners can determine if you’re able to see the road clearly enough to be acceptable. Do not worry if you don’t have perfect vision because you can still use eyeglasses or contact lenses on this part of the exam so you can see clearer.

If you are able to pass the exam and get your license while using corrective lenses, the fact that you needed them will be indicated somewhere on your license. This means if you ever get pulled over by the authorities in the future, make sure you are wearing your corrective lenses or else you might get penalized more for not wearing them.

Most of the practical exam will be answering safety questions that the examiner asks you and then driving in your vehicle with them. Basically, the examiner will ask you what safety checks you should perform before driving the vehicle and how to tend to any maintenance issues that the vehicle may need. Their questions consist of “show me” questions and “tell me” questions. For example, the examiner may want to see if you know how to check the oil of your vehicle. So, they’ll ask you to show them where the oil filler cap is located. After you do that, you’ll then tell them how you would check the level of oil after removing the cap.

You need to have perfect knowledge of basic safety inspections and how to perform a vehicle safety check. The examiner might not necessarily test you on every aspect of safety, but you should be prepared for anything because the questions will be random. Therefore, make sure you have studied your academic literature on vehicle safety checks and inspections because that knowledge will be crucial in passing this part of the exam.

The next part of the practical driving test is the actual driving part. This is where you get in a vehicle with your examiner and they give you directions on where to go as you drive. They will be watching for how you handle the vehicle under various driving conditions, such as heavy traffic, highway driving, and so on. Be prepared to be tested on your reversing skills because they’ll likely have you reverse the vehicle into a parking space or even around a corner.

Lastly, there is an independent driving test where you drive on your own and go in a series of directions that are given to you by your examiner beforehand. This is different than the first driving part because here you are getting all the directions at once before you start driving. Before, you were getting the directions in real-time as you were driving the examiner around. The purpose of the independent driving test is so the examiner can see that you can handle a driving scenario without anyone telling you what to do in the vehicle. After it is over, they will ask for your feedback about the experience. You have a high chance of failing, but as long as you give it your all – don’t worry about it. I used a test scanner to find multiple tests before I actually passed.

Overall, you need to prepare for this test by getting as much driving practice on the road as possible. You need to feel completely comfortable behind the wheel and performing all types of driving. The examiner watches for every little mistake that you make, including how long you wait at stop signs. So, keep safety in mind at all times and you should have a good chance of passing this practical test.

Parking Sensors in Your car

As the car reverses into a space and moves closer to objects, an audible buzzer beeps more frequently.

This is usually achieved by four ultrasonic parking sensors fitted into the bumper of the car. They send out an ultrasonic wave, and if this hits an object, it bounces back to the same sensor. Information received is then relayed to the brain, allowing it to make the buzzer sounds.

For most vehicles the shape of the car will determine where sensors are fitted. This is due to wide differences in design, between manufacturers and models of vehicles.

For cars with a center panel and separate corner bumper pieces that curve around the car, two low and two higher sensors are often necessary. If a vehicle has a metal panel behind the bumper, this usually means holes must rise above the obstruction, also avoiding interference issues.

Factory fitted parking sensors are the ones fitted to a car at the time of manufacture. Retrofit, often called ‘After-market’, are the ones fitted at some time after the vehicle was produced.

Factory fitted sensors have a certain look, devised by the car designer, which is difficult to recreate in aftermarket sensors. Retrofit devices are made for all cars from all manufacturers, and consequently have their own distinctive look.

It could be argued that some of the latest aftermarket designs are better due to their small, discreet shape. They are also constantly being redesigned for better looks or usage, and not devised and forgotten like factory ones.

Sensor heads are getting smaller. Small is definitely less intrusive although they may have limited colour options, for example only available in black or silver.

Generally it is best to go for the smallest sensor heads possible, as once a hole is drilled it cannot be made smaller.

Maintaining Car Interior

Bring a Trash Bag

Often, piles of garbage will pile up in an automobile and its owner may not have the time or the patience to clean it all out. This all-too common situation can be avoided if there’s already a place to put trash. Putting any waste in one convenient receptacle will also preserve an interior’s appearance, to a certain degree. A full bag of trash might not be the prettiest sight in the world, but it beats an arbitrarily arranged pile of junk.

Keep Cleaning Materials in the Glove Box

Plenty of products are custom made to remove stains from automobile interiors. Why not keep something on hand so spills can be stopped before becoming permanent eyesores? CNN even recommends keeping toothpaste in the glove compartment. Of course, that’s also handy if you happen to need to freshen up at some unexpected point during your travels.

Don’t Smoke Inside The Car

It’s a well-established fact that smoking can lead to serious damage to anyone’s health. But a car filled with cigarette smoke can cause a yellow or brownish veneer to develop on upholstery. For that matter, a dropped cigarette can leave burn marks on carpets or sears or even cause an accident in a worst-case scenario. Refusing to smoke inside a car will not only prevent these problems but it could even help a smoker cut down and may even eventually break the habit.

Keep Kids Accountable

CNN also points out that youngsters aren’t always the greatest at picking up after themselves. For moms and dads who spend lots of time driving, the news source recommends a “Bring It In, Take It Out” policy. That way, families can guarantee that backpacks, lunch boxes or whatever other accoutrements wee ones carry won’t turn into car clutter.

Replacement Car Key

If you find yourself in a situation when you need a replacement car key, by far one of the most widespread solutions is to determine if you have a spare set of keys. But if that is not a viable option, the second thing that you can try is to get in touch with your car dealership. In most cases, your car dealer will be able to easily replace your lost keys. But while having your keys replaced by your car dealer is a surefire option, one of its biggest caveats is that it may cost you an arm and leg. If your vehicle is a bit on the modern side, then this means that your keys will most likely contain special computer chips and require special programming. And because of that fact, be ready to shell out as much as $200, which most people would agree is kind of steep. Most of the expenses are for the programming the electronic chip.

So you ask, which is the most economical solution for a replacement car key? There are a few things that you can try in this case. Probably your best bet is to purchase a replacement from your friendly neighbourhood locksmith. Yes, a qualified locksmith is capable of making a replacement set of keys for clients who have lost theirs. They have the experience, expertise and the right tools that will enable them to create replacements. And the best part is, they can do this for a fraction of the price as compared to the price that is being charged by most car dealers. But calling a locksmith is not exactly a foolproof option because not all of them are proficient when it comes to making replacement car keys.

All about Car Wax

It is easier to use your own resources at home to wash the car instead of taking the car to a car wash where apart from the costs incurred to wash the car also in some cases the cleaning might not be up to your standard hence you will be forced to redo the work again. The best advice is washing the car at home which is cheaper and easier and also you can tell where the dirt is and can always do the work as many times as possible.

Once the cleaning is done then you will be required to wax the car. When it comes to waxing one of the reason your car will deserve this utmost care is because of the paint on the car. Every single day that you are using the car you will be exposing it to numerous version and types of weather from rain, snow to sun with each competing to destroy the paint done on it. All this at the end of the day will either change the painting or even in extreme cases the paint will start peeling off. This implies the wax is an important aspect for cleaning the car, and you will be assured of that polished finish on the car once the car has been waxed.

When it comes to waxing the car and the car wax, there are various types of the wax that you need to consider, for example we have the natural wax that is got from natural products be it honey or even plants. One of the characteristics of the natural wax is that it is expensive since they are the best in the market and provide long durability time for the car paint and therefore it will be money’s worth when bought. Another wax type is the synthetic wax which is manufactured without the natural products, this means that it is on a large scale market and hence cheaper than the natural one although in terms of durability it is not as comparable as natural one.

Waterproof Car Seat Covers is So Important

Waterproof covers on every car seat tend to be much stronger and more durable than untreated fabric covers which can easily rip or tear under too much stress. Car owners who have pets or children or both, quickly find out just how beneficial waterproof covers are. They are strong enough to resist tearing after being subjected to the constant and active motion of children and pets. Children often enjoy eating snacks while riding as passengers in the car as well as drinking beverages to pass the time. And they are not always careful to avoid having drops of food or liquids spill onto the seat coverings.

Waterproof covers won’t absorb the food crumbs and soda spills so often associated with having children as passengers in the family car. All it takes is one small stain to be absorbed into unprotected fabric, and not only does the car begin to look sloppy, there is also the expense of having to get the stain professionally treated to get the seat covering looking fresh and clean again. With waterproof covers, no moisture or liquid can penetrate the fabric. A quick mop up with a damp paper towel restores the surface of the cover to like-new condition.

Waterproof seat covers for cars come in a variety of colours to suit the overall decor, including solid colours as well as patterns. If a vehicle does not come with waterproof coverings, there are plenty of reliable car cover vendors online that can custom-make waterproof covers to protect your investment and keep the car’s interior looking fresh and clean as long as possible.

Effect of Wheel Size

Typically, someone wishing to plus-size starts from a 15- or 16-inch standard wheel size and upgrades to a 17-, 18- or 19-inch diameter. As wheel size increases, tire diameter decreases to maintain the same overall diameter, ensuring proper clearance, gearing and speedometer readings. Large diameter wheels and tires are often only available in increased widths, so plus-sizers must take their wheel well and fender depth into consideration as well. A manufacturer’s car wheel size guide can help determine what sizes will fit your make and model.

As to performance, increasing the size of your wheels has both benefits and drawbacks. On the plus side, tires with shorter sidewalls can improve steering response and cornering stability. Increasing the wheel diameter and width may also increase traction. On the downside, larger tires mean more weight. More weight hurts fuel efficiency, acceleration and stopping distance. Wider tires have a tendency to float, reducing traction in inclement weather. Perhaps the biggest downside to plus-sizing is the reduced durability of the tires themselves. Narrow tire sidewalls don’t have the strength of standard tires and can be damaged by potholes and road debris. They can also sustain damage from getting pinched more easily.

Numerous wheel size comparison road tests give 17-inch and 18-inch wheels and tires the highest ratings, citing good grip, steering, braking and a comfortable feel. Upgrading from a 17- to 18-inch diameter had negligible effects on ride quality and offered additional grip. Heavy 19-inch wheels and tires fared the worst in road tests, straining the suspension and increasing impact harshness. In contrast, 15- and 16-inch standard wheel sizes were the quietest and had the smoothest ride, but had slightly more understeer on the skidpad.

All about Automotive Fire Safety

· If you are driving a moving vehicle, get over to the rightmost lane or the shoulder. You want to exit the car without running into moving traffic. Use your blinkers to quickly switch lanes. If you have installed a loud air horn kit, sound it.

· Stop the car and turn off the engine. This will keep the car from pumping additional gasoline into the fire and will turn off the electrical systems.

· Get yourself and your passengers out of the car as quickly as possible. Stay clear of moving traffic.

· Run away from the car, waving your hands to warn oncoming traffic to move to the left. Run in the direction of oncoming traffic so that you can warn it. Don’t even think about trying to salvage anything “valuable” from the car unless it’s breathing.

· Call 911 or the fire department on your cell phone. Do NOT attempt to extinguish the fire – the fire may instead extinguish you.

While gas tanks do indeed explode, it is rare. More likely is that some fluids in the engine may ignite. Tires are also dangerous. When they get hot, they start exploding, spewing burning rubber everywhere. This is reminiscent of a napalm attack. And if that isn’t bad enough, batteries can also explode, sending acid and shrapnel flying. Air bags may deploy, sending burning plastic into the surroundings. A hellscape of burning fluids, rubber, glass and shrapnel, accompanied by an acid bath, should be enough to get you running for your life. Toxic clouds may follow you as you escape, so get far away from the scene. Lung damage from breathing in hot gases can kill you. Carbon monoxide rising from the burning wreck can suffocate you. Be grateful you escaped with your life. Don’t forget to contact your insurance agent once the danger has passed.

Performance Superchargers

The difference between the two types of superchargers is in the method of air compression. The first type is positive displacement. Positive displacement superchargers deliver pressure at a constant, almost fixed rate at all speeds and are normally mechanically powered. The air is divided within the supercharger and deposited bit by bit into the engine. Positive displacement superchargers have four main types of pumps; Roots, Lysholm twin-screw, sliding vane, and scroll-type supercharger or G-Lader. The pumps break down further into external and internal compression pumps.

Roots superchargers have external compression pumps. These pumps allow the pressure in the intake manifold to overcome the pressure coming from the supercharger which causes pressure to backflow into the supercharger. The backflow pressure is what compresses the gas power. These pumps are not as efficient as internal compression but are efficient in moving air at low pressure differentials.

The other types of positive displacement pumps use internal compression to some extent. Internal compression pumps compress the air within the supercharger and deposit it into the engine smoothly at a fixed compression ratio. The compression ratio should favor the supercharger because if the boost pressure of the engine exceeds the compression pressure of the supercharger, backflow will occur that takes away from the efficiency of the engine. Internal compression superchargers should match or exceed the pressure of the engine for maximum efficiency.

The other type of superchargers is dynamic compressors. Unlike positive displacement superchargers, dynamic compressors deliver higher pressure at higher speeds and are normally powered by gas turbines. They excite the air to a high rate and exchange the speed with the engine for air pressure. Therefore, the more pressure within the engine, the more air velocity the supercharger will produce to exchange with the engine.

Superchargers and turbochargers both work to increase the power output of an engine but are powered differently. The main difference is that superchargers are powered directly by the engine while turbochargers are powered by the exhaust from the engine. Turbochargers can gain more power and higher fuel efficiency than superchargers but superchargers have higher throttle response and can reach top speeds faster. This is because turbochargers feed off of the exhaust which is not strong enough at first to power a turbocharger until it reaches a high RPM. When the exhaust is strong enough to start the turbocharger, the boost causes even more exhaust to give the turbocharger more power, causing a sudden surge in speed and power output after a slow start. Turbochargers do not apply boost in proportion to the RPM like superchargers.

Optimal Vehicle Protection

The wind and dirt can result in minor scratches often penetrating the paintwork of the body. Where dust accumulates and covers the surface, it will contribute to a considerably dull appearance. Bird droppings can result in increased exposure to acidity. While parking under a tree can provide shade, it can also expose vehicles to an onslaught of leaves, twigs, berries, and sap.

Thieves will often think twice before targeting a covered motor vehicle, in comparison to assets that are fully exposed. The fabric that is secured around the automobile will mean that it should take a longer period to access the particular car. There are customized covers that include a lock and key, making it even harder for possible criminals to attempt to break into the automobile.

Custom fitting options have become increasingly popular as it eliminates the possibility of a poor fit. Tailored wraps are manufactured to align with the shape and the size of the vehicle. Many include pockets for mirrors for increased security and appeal. Options such as tie downs, cords and locks will prevent strong winds from removing the wrap and ensure that the car remains protected against the elements.

The key to maintaining the appeal of the vehicle is to ensure that it remains protected and is not susceptible to fading, scratches, dings and exposure to UV light. Dust allowed to settle on the surface will contribute to minor scratches, which may be prevented with adequate coverage. There are a number of benefits associated with the right type of car covers custom made to fit your automobile.
