What speed should you aim for on a highway entrance ramp?

Reach at or near traffic speed before merging.

  1. Walking speed
  2. At or near traffic speed ✔
  3. Exactly half the speed limit

Why: Use the acceleration lane to approach the speed of highway traffic. Then choose a safe gap and merge without forcing others to brake.

Huh, didn't know that: A ramp speed sign may warn about a curve before the acceleration lane begins.

The dad joke
The entrance ramp warmed up before joining the highway team.
