Yellow diamond warning signs alert you to hazards before you can see them. When you pass one, slow down and watch for other markings, signs, signals or work zones that may follow. These signs cover speed changes, lane changes, hills and who else might be on the road.

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.

An Advisory Speed sign at a highway exit indicates what?
  1. The maximum safe speed for that exit
  2. The minimum legal speed on the exit ramp
  3. The speed limit for the entire highway
  4. The recommended speed in wet weather only

Answer: The maximum safe speed for that exit

An Advisory Speed sign shows the maximum safe speed for a highway exit.

Handbook p. 10 ↗
When you see a Merge sign, who is responsible for merging safely?
  1. Only the driver in the ending lane
  2. Drivers in both lanes
  3. Only the driver in the continuing lane
  4. The driver who is farther behind

Answer: Drivers in both lanes

At a Merge sign, two lanes become one, and drivers in both lanes are responsible for merging safely.

Handbook p. 10 ↗
At a Lane Reduction sign where the right lane ends, what should drivers in the left lane do?
  1. Speed up so merging drivers fall in behind
  2. Allow vehicles from the ending lane to merge smoothly
  3. Move into the ending lane to make room
  4. Hold their position; merging drivers must wait

Answer: Allow vehicles from the ending lane to merge smoothly

When the right lane ends, drivers there must merge left, and drivers in the left lane should allow vehicles to merge smoothly.

Handbook p. 10 ↗
What must you do when passing horse-drawn buggies?
  1. Honk once, then pass with three feet of clearance
  2. Slow down and pass with at least two feet of clearance
  3. Stay behind it until it pulls off the road
  4. Slow down, don't honk, and pass with 3+ feet of clearance

Answer: Slow down, don't honk, and pass with 3+ feet of clearance

State law requires passing horse-drawn buggies with at least three feet of clearance; slow down and don't use the horn.
