Lines on the road tell you which way traffic flows and whether you may pass or change lanes. Color tells direction; solid or broken tells permission. Lane signs and arrows tell you where a lane must go.

Know the rule

Overhead lane signs tell you which way you must go. If the sign says ONLY, you must go the way the arrow points. Arrows painted on the road mean the same as overhead arrows.

Lane use control signs
Lane-use signs: must turn left; turn left or go straight (right turn prohibited); must turn right

Lane

A section of roadway for a single line of vehicles.

Handbook p. 92 ↗

Know the rule

On a two-lane road (one lane each way), drive on the right and yield the left half of the roadway to oncoming traffic.

Handbook p. 63 ↗

Choosing a lane on multilane roads:

  • Drive in the lane with the smoothest flow; it keeps a safe space cushion and saves gas
  • With three or more lanes one way, the middle lane or lanes are usually smoothest
  • The left lane is for drivers who want to go faster, pass or turn left
  • Slower drivers and those turning right use the right lane
  • With two lanes one way, the right lane is usually smoothest
  • Where there are special left-turn lanes, the left lane may be smoothest
