New York DMV Permit Written TestRules of the Road and Traffic LawsHard

You are driving on a four-lane highway with two lanes going in each direction. If you are not passing and traffic is moving freely, which lane should you generally use?

  1. AEither lane, as long as you maintain the speed limit.
  2. BThe right-most lane.
  3. CThe center lane, if available, for optimal visibility.
  4. DThe left-most lane, as it is typically faster.
Show answer & explanation

Correct answer: B. The right-most lane.

In New York State, as in many places, the general rule on multi-lane highways is to 'keep right, pass left.' This means that if you are not actively passing another vehicle, you should stay in the right-most lane to allow faster traffic or those who wish to pass to use the left lane(s).

Why the other options are wrong

  • A. This can lead to 'left-lane hogging' and impede traffic, even if you are at the speed limit.
  • C. On a four-lane highway (two in each direction), there is no 'center lane' for a single direction of travel. This concept applies more to a six-lane highway (three in each direction).
  • D. While it may be faster, it's generally reserved for passing and should not be used for continuous travel.

Keep Right Rule

A traffic law requiring drivers to stay in the right-most lane available for travel, reserving left lanes for passing.

  • Applies on multi-lane highways.
  • Promotes efficient traffic flow.
  • Reduces road rage and unsafe passing maneuvers.
  • Exceptions: passing, preparing for a left turn, or right lane is obstructed.

Memory trick: Right is bright, for continuous light!
