The biggest factor in all of the mistakes that a new driver can make during a driver's inability to stay calm. Read through this section to familiarize yourself with possible common mistakes that can take place during the road test. Know what to expect. Note that driver's test is broken down into multiple parts, during which, points are deducted for failure to perform each part of the maneuver or action. A loss of enough points will conclude the test and result in immediate failure.
Inability to start the vehicle Make sure that you are capable of turning the car on. If you are unfamiliar with the vehicle you are about to drive, try to familiarize yourself with it before you start taking the road test. If it is a rental car from your driver's school, you should probably buy one extra lesson right before the road test so that you know the vehicle well, and feel comfortable in it.
Failure to release parking brake When you first get into the car, the parking brake will most likely be on. Do not forget to put the lever down to release the break. You don't want to start driving with the break on!
Failure to fasten seat belt Actually, make sure that this is the first thing you do when you get in the car. Try to make it a habit. As soon as you are getting in the car, clip the seat belt. It doesn't matter if you are about to start driving or if you're planning to sit around for the next 10 minutes. Put the seat belt on - it won't hurt.
Failure to wear glasses (if applicable) Even if you normally wear contact lenses, it is recommended that for the test itself you wear glasses instead. The odds of a contact lense falling out are very unlikely, but why tempt your luck. If you need glasses to drive - put them on.
Failure to use proper signal As soon as you start driving, most likely you need to signal to get into traffic, but if not, there will be many chances to fail to do so. Signal at each turn and when parking. Let the other drivers know what you're doing.
Clutch/gear control (if applicable) Could be easily avoided if you rent an automatic, but lets say you are using your family car for the lesson that has manual gear control - be sure that you know how to use the clutch and gear shifting properly. Making engine stall is not a good start for the road test.
Crossed solid traffic line Watch out fot the solid lines. If you cross that line you cannot explain yourself by saying "But the guy in front of me did the same." Drive safe, pay attention to others, but do not make the same mistakes as others.
Drove in improper lane Well, lets hope this is not the case. Stay on your right.
Failed to observe traffic Pay attention to traffic signals at all times. The only exception would be if there is a traffic attendant placed at the cross-section. Listen to his directions instead.
Jumped curb This one is not easy to prepare for other than practicing enough behind the wheel. Some students find it difficult to tell the distance between the right wheel and the curb. Each car is different, but with enough practice, you shouldn't have any problems keeping a safe distance from the curb while driving.
Unable to park in 3 minutes This is not an exact math. Most of the states require the student to be able to park the car. Some of the state require the student to be able to parallel park the car on the street. There is usually a time limit (or attempts limit) per test. If you need to know how to do so, practice enough times before the driving exam. It would be a shame to pass everything and get left behind because of this little detail.
Passed stop sign Pay attention to all stop signs, sometimes these may be in form of a sign on the corner of the street, but they may also be painted on the road itself. If it says stop - stop! It doesn't mean slow down. Stop. Wait a second so that your examiner can note that you have definitely stopped, and then and only then, if there are no cars coming would you continue on driving.
Steering It's never a good sign when your examiner needs to tell you to stear away, or grabs the steering wheel from you, or sometimes, if the car has dual controls, grabs the controls away from you. In most of the states you would get one warning, but if occurs again, you will fail your driving exam.
Brakes Same as above. Make sure you drive safe. Be cautious. And most of all remember, the faster you drive, the harder it is to stop.
Accelerator You should never go faster than the posted speed limit, but you should also keep in mind that if you are planning to go through the entire exam by going 5 miles an hour, you will be told to speed up. Maintain reasonable speed for the area that you are driving in and you will be fine.
Unable to turn engine off Yes, the examiners do wait for you to turn that engine off once the exam completes, so do it. Set the handbreak while you're at it, just to be sure, and keep your seat belt on until you are ready to leave the car.
And of course the disqualifying violations include: accidents and dangerous actions
