If there is a train coming, get out of the vehicle and run along the side of the tracks toward the train, to avoid being struck by the debris from the accident.


#14. Which car or cars are best positioned for a left turn on this one-way street?

When making a left turn from a one-way street, get into the lane furthermost to the left well ahead of the turn. Do not start the turn at the edge of the intersection. Instead, drive into the intersection and turn sharply into the lane shown.

Remember to turn from the lane that is closest to the direction of travel and turn into the lane closest to the lane from which the turn is initiated. Do not turn from the middle lanes.

The passing score in District of Columbia is 80 percent, which means you must answer at least 20 of these 25 DMV questions correctly. Aim a little higher when you are studying and preparing for the exam. You have a much better chance of passing the examination, if you can reach a score of 100%.

You Should Always Read the D.C. Driver’s Manual

Studying the D.C. Driver’s Manual is a must for successfully passing the driver knowledge test.

You can get a PDF-version of the manual online from or from your local Service office .

Always start by reading the manual. Then, use these practice tests to check how much you have learned and if you are ready for the real exam or not.

Don’t use the practice tests instead of the manual, even if friends and some less committed websites suggest such a strategy. The best way to learn is to put the rules of the road in a context and not simply try to memorize questions and answers.
