California DMV Freeway Driving Practice Questions (2026)
Freeway questions cover merging, exiting, lane use, HOV lanes, and what to do if your car breaks down. The key rule: when merging, highway traffic has the right-of-way, so enter at or near the speed of traffic and do not stop unless absolutely necessary.

1While you're driving in the rightmost lane of a highway, you should:
- A Drive slower than every other car around you
- B Watch for cars merging in from the on-ramps
- C Drive faster than every other car around you
- D Stop to help any stranded vehicles, since the law requires it
Show answer and explanation
Correct answer: B — Correct. Per the handbook, even when you have the right-of-way, "make space for vehicles entering freeways."
Why the other options are wrong
- A Incorrect. No rule says you must drive slower than everyone else in the right lane. Keep up with the flow of traffic; it is just that slower vehicles should keep right.
- C Incorrect. The right lane is for slower traffic and vehicles entering and exiting. You should not drive faster than others there, and you must obey the speed limit.
- D Incorrect. The law does not require drivers to stop and help stranded vehicles, and stopping on a freeway shoulder is dangerous in itself.

2When the on-ramp is very short, what's the safest way to merge into traffic?
- A Speed up gradually so other drivers notice you
- B Use the freeway's left lane to get up to traffic speed
- C Wait for a bigger gap to open up, then accelerate quickly into it
- D Rely on the ramp itself to bring you up to highway speed
Show answer and explanation
Correct answer: C — Correct. When the on-ramp is too short to fully accelerate, wait for a big enough gap and then accelerate quickly to merge; the handbook says to merge only with enough space and at or near the speed of traffic.
Why the other options are wrong
- A Incorrect. The key to merging is reaching the speed of traffic with a big enough gap; speeding up gradually so others see you does not guarantee a safe merge.
- B Incorrect. Per the handbook, use the right lane to enter or exit traffic; the left lane is for passing, and you cannot use it to get up to speed.
- D Incorrect. The question says the acceleration lane is very short, so it cannot get you up to highway speed; relying on the ramp works only for a normal-length acceleration lane.
Handbook: §6 Merging
3You're in the innermost fast lane of an 8-lane divided highway and need to leave at an exit ahead on the right. What's the right approach?
- A Check traffic once, then cut across every lane in a single move
- B Move over one lane at a time until you reach the rightmost lane
- C Push your speed 50 mph above the limit and blast across all the lanes
- D Slow way down first, then carefully change lanes one by one
Show answer and explanation
Correct answer: B — Correct. Per the handbook, when you need to cross several lanes, signal and cross them one at a time, checking your blind spot for each lane change.
Why the other options are wrong
- A Incorrect. The handbook says that when you need to cross several lanes, signal and cross them one at a time, checking your blind spot each time.
- C Incorrect. Going 50 mph over the speed limit is a serious violation and extremely dangerous.
- D Incorrect. The handbook notes there is no need to slow down before changing lanes; slowing down in the fast lane disrupts traffic. Keep your speed and change lanes one at a time.

What you need to know
- When merging, highway traffic has the right-of-way: be in the proper lane, get to or near the speed of traffic, and do not stop unless absolutely necessary. §6
- Leave three seconds of space between you and the vehicle ahead when merging; if you need to cross several lanes, cross them one at a time and check blind spots each time. §6
- When in the proper lane, signal five seconds (about 400 feet) before you exit, and do not cross any solid lines when entering or exiting. §6
- To merge into highway traffic you need a gap of about a full block, roughly 300 feet (half a block, about 150 feet, on city streets). §6
- The far-left lane is the Number 1 Lane, then Number 2, and so on. Use the left lane to pass; if you drive slower than other traffic, use the right lane. §6
- HOV (carpool) lanes are marked with a diamond symbol; do not cross double solid lines to enter or exit them — use designated entrances and exits. §6
- If you tow a trailer or drive a truck with three or more axles, use the far-right lane or a lane marked for slower vehicles; with four or more lanes and no markings, use only the two right-hand lanes. §7
- If your vehicle breaks down on the freeway, pull onto the right shoulder, exit on the right side if you must get out, dial 511 or use a call box, and stay inside with your seat belt on until help arrives. §8
Common traps on the test
- Stopping at the end of the on-ramp to wait for a big gap — you should merge at traffic speed and stop only if absolutely necessary.
- Crossing double solid white lines to get into or out of an HOV lane or onto a ramp — never change lanes over double solid white lines.
- Backing up or making a sudden move after missing an exit — keep driving until you can safely and legally turn around.
FAQ
How far before a freeway exit should you signal?
Once you are in the proper lane, signal five seconds before you exit, which is about 400 feet.
What should you do if your car breaks down on a California freeway?
Pull over to the right shoulder, exit on the right side if you must get out, call 511 or use a call box, and stay in the vehicle with your seat belt on until help arrives, unless it is safer to get out and stay away.
