Expressways are fast and busy, so merging, lane choice and exits need planning. At night your vision shrinks to your headlights, and glare can blind you. Rural roads bring hidden intersections and sharp curves.

Know the rule

Expressways, interstates, toll roads, turnpikes and freeways are fast, multi-lane roads with maximum limits of 55, 65 or 70 mph.

Handbook p. 89 ↗

Know the rule

Entering an expressway, use the speed-change lane to build speed. Signal, look for an opening, match the speed of traffic, and merge when it's safe.

On the expressway:

  • Check mirrors and use turn signals when changing lanes
  • Don't follow too closely
  • Right lane is for slower traffic; left lane for faster traffic and passing
  • Don't drive continuously in the left lane
  • Never stop on the expressway; pull off, lift the hood and turn on hazard flashers
  • Never walk along an expressway
Handbook p. 89 ↗

Exits and lane reductions:

  • Exits may be on the right or left; get in the correct lane and signal
  • Slow down for the exit in the speed-change lane
  • Missed your exit? Go to the next one. Backing up on an expressway is illegal
  • Lane closed ahead: merge early if traffic is light; in dense, slow traffic, zipper merge

Know the rule

Never overdrive your headlights. Keep them clean and properly aimed, and use them from sunset to sunrise.

Night driving:

  • Dim the dashboard lights and avoid other interior lights
  • Use the sun visor against glare
  • Use edge lines and center lines as guides
  • Don't stop on the roadway; if you must, a red warning light is recommended
Handbook p. 90 ↗

Know the rule

Rural intersections may or may not have signs, and other drivers can be hard to see. Slow down and look both ways before entering any rural intersection.

Handbook p. 90 ↗

Know the rule

Slow down before a curve. Don't brake suddenly, which can cause skidding or locked wheels, and never cross the center line.

Handbook p. 90 ↗

Know the rule

If a vehicle is coming head-on in your lane, slow down, pull to the right, and sound your horn.

Handbook p. 90 ↗

Put it into practice

You miss your exit on the interstate. Don't stop or back up on the shoulder. Continue to the next exit and turn around there.
