DMV Permit · General

A driver is on a highway on-ramp preparing to merge. What is the proper merging technique?

Correct answer

Signal early; match the speed of highway traffic while still on the on-ramp; find a gap in traffic; merge smoothly at highway speed — do not stop on the on-ramp unless absolutely necessary; yield to highway traffic

  1. A Stop at the end of the on-ramp and wait for a gap
  2. B Signal early; match the speed of highway traffic while still on the on-ramp; find a gap in traffic; merge smoothly at highway speed — do not stop on the on-ramp unless absolutely necessary; yield to highway traffic
  3. C Turn on hazard lights and merge regardless
  4. D Merge as slowly as possible to force cars to make room

Why this is the answer

HIGHWAY MERGING TECHNIQUE: The on-ramp is an ACCELERATION LANE — use its full length to match highway speed; STEPS: Signal your intent to merge early; accelerate to match highway traffic speed; look for a gap (check mirrors, blind spot); merge smoothly into the gap; cancel signal; do not stop at the end of the on-ramp — a stopped vehicle attempting to merge onto 65 mph traffic is extremely dangerous; DO NOT: Force other vehicles to brake; merge too slowly (causing speed differential); merge too fast; HIGHWAY DRIVERS' RESPONSIBILITY: When approaching a merging vehicle, adjust speed to facilitate the merge if safely possible — move to another lane (Move Over law applies to emergency vehicles; courtesy applies to merging vehicles); Do not speed up to prevent merging; COMMON ERROR: Stopping at the bottom of the ramp waiting for a gap — creates a dangerous low-speed/stopped vehicle on a high-speed approach.
