Passing is one of the riskiest moves you'll make, especially on two-lane roads where you borrow the oncoming lane. Pass only when you won't interfere with oncoming traffic or the vehicle you're passing, and get it done quickly.

Know the rule

You must not make another driver slow down or pull over so you can finish your pass. Complete the pass before coming within 100 feet of any vehicle approaching from the opposite direction.

Handbook p. 75 ↗

It's against the law to pass when:

  • A hill or curve blocks your view
  • There's a solid yellow line in your lane
  • You're within 100 feet of an intersection or railroad crossing
  • You're within 100 feet of a bridge or tunnel
Handbook p. 75 ↗
Situations where passing is prohibited (composite)
Do not pass in these situations

Know the rule

You may pass on the right only where there are two or more lanes moving in your direction. Never pass on the right by driving onto the shoulder, paved or not.

Handbook p. 75 ↗

Know the rule

On multilane roads, the left-most lane is meant for passing slower vehicles. A driver you pass on the right may not see you and could change lanes.

Handbook p. 76 ↗

Know the rule

Don't pull up close behind the vehicle you plan to pass, especially a large truck or bus; it blocks your view. Follow at a safe distance until you can see far enough ahead.

25 seconds

An oncoming vehicle farther away than this appears to be standing still

Handbook p. 76 ↗

Know the rule

If you can actually see an oncoming vehicle getting closer, it's probably less than 25 seconds away. If you see an oncoming vehicle, don't attempt to pass.

Handbook p. 76 ↗

To pass safely:

  • Check for oncoming traffic, cars entering from side streets, and your mirrors and blind spot
  • Signal; a light tap of the horn keeps the other driver from being surprised
  • Start from at least two seconds behind the vehicle you're passing
  • Steer smoothly into the passing lane and don't drift toward the other vehicle
  • Return only when the passed vehicle's whole front shows in your rearview mirror; signal first
Handbook p. 77 ↗

Know the rule

Pass as quickly and safely as possible; the longer you're alongside, the longer you're in danger.

Handbook p. 77 ↗

Know the rule

When someone is passing you, slow down a little and, on a two-lane highway, move as far right as you safely can.

Handbook p. 77 ↗

Put it into practice

On a two-lane road you're stuck behind a slow tractor, 90 feet from a bridge. Even with no oncoming traffic, you can't pass: it's illegal within 100 feet of a bridge. Wait until you're past it and the road ahead is clear.

Check your understanding

Read the question, decide on an answer, then open it to check the explanation. These are Roadwise study questions based on the source handbook.

You should complete a pass before coming within how many feet of a vehicle approaching from the opposite direction?
  1. 100 feet
  2. 50 feet
  3. 200 feet
  4. 500 feet

Answer: 100 feet

Passing must be completed with at least 100 feet of clearance before meeting oncoming traffic.

Handbook p. 75 ↗
It is illegal to pass another vehicle within 100 feet of:
  1. A parked vehicle
  2. A bridge or tunnel
  3. A business driveway
  4. A speed limit sign

Answer: A bridge or tunnel

Passing is prohibited within 100 feet of an intersection, railroad crossing, bridge or tunnel.

Handbook p. 75 ↗
When is it legal to pass another vehicle on the right?
  1. Only on rural two-lane roads
  2. Anytime the shoulder is paved
  3. With two or more same-direction lanes
  4. Only on one-way streets

Answer: With two or more same-direction lanes

Passing on the right requires two or more same-direction lanes; the shoulder can never be used to pass.

Handbook p. 75 ↗
An oncoming vehicle that is how many seconds away generally appears to be standing still?
  1. More than 5 seconds
  2. More than 60 seconds
  3. It never appears to stand still
  4. More than 25 seconds

Answer: More than 25 seconds

Vehicles more than 25 seconds away tend to look motionless, which is why misjudging oncoming traffic is dangerous.

Handbook p. 76 ↗
If you can actually see an oncoming vehicle getting closer while deciding whether to pass, what does that suggest?
  1. It's under 25 seconds away; don't pass
  2. It's over 25 seconds away; pass
  3. It's slowing to let you pass
  4. It's safe to pass if you signal

Answer: It's under 25 seconds away; don't pass

If movement is visible, the vehicle is likely under 25 seconds away and passing would be unsafe.

Handbook p. 76 ↗
What should you do before pulling back into your lane after completing a pass?
  1. Merge back immediately after your front bumper clears theirs
  2. Signal, then merge without checking your mirror
  3. See the passed car's whole front in your mirror
  4. Tap your brakes to alert the other driver first

Answer: See the passed car's whole front in your mirror

You should see the full front of the passed vehicle in your mirror before safely returning to your lane.
