The Rules For The Driving Portion Of The CDL Exam

You will drive over a test route that has a variety of traffic situations. At all times during the test, you must drive in a safe and responsible manner. You must wear your safety belt, obey all traffic signs, signals and laws and complete the test without an accident or violation. No radios, electronic devices or phones may be on during the test.

During the driving test, the examiner will be scoring you on specific driving maneuvers as well as on your general driving behavior. You will follow the directions of the examiner. Directions will be given to you so you will have plenty of time to do what the examiner has asked. You will not be asked to drive in an unsafe manner.

If your test route does not have certain traffic situations, you may be asked to simulate a traffic situation. You will do this by telling the examiner what you are or would be doing if you were in that traffic situation.

When ready to turn:

  • Check traffic in all directions.
  • Keep both hands on the steering wheel during the turn.
  • Keep checking your mirror to make sure the vehicle does not hit anything on the inside of the turn.
  • Vehicle should not move into oncoming traffic.
  • Vehicle should finish turn in correct lane.

Driving Through Intersections

As you approach an intersection:

  • Check traffic thoroughly in all directions.
  • Decelerate gently.
  • Brake smoothly and, if necessary, change gears.
  • If necessary, come to a complete stop (no coasting) behind any stop signs, signals, sidewalks or stop lines maintaining a safe gap behind any vehicle in front of you.
  • Your vehicle must not roll forward or backward.
  • When driving through an intersection:

  • Look and listen for the presence of trains.
  • Check traffic in all directions.

Do not stop, change gears, pass another vehicle, or change lanes while any part of your vehicle is in the railroad crossing.

School Bus Or Placarded Vehicle

If you are driving a bus, school bus, or vehicle displaying placards, be prepared to observe the following procedures at every railroad crossing (unless the crossing is exempt):

  • As the vehicle approaches a railroad crossing, activate the four-way flashers.
  • Stop the vehicle within 50 feet but not less than 15 feet from the nearest rail, place the bus in park/neutral and set the parking brake.
  • Listen and look in both directions along the track for an approaching train and for signals indicating the approach of a train. If operating a bus, you may also be required to open the window and door prior to crossing tracks.
  • Keep hands on the steering wheel as the vehicle crosses the tracks.
  • Do not stop, change gears, or change lanes while any part of your vehicle is proceeding across the tracks.
  • Four-way flashers should be deactivated after the vehicle crosses the tracks.
  • Continue to check mirrors and traffic.

Not all driving road test routes will have a railroad crossing. You may be asked to explain and demonstrate the proper railroad crossing procedures to the examiner at a simulated location.
