California Car / Permit practice question · Sharing the Road

You come up behind a vehicle displaying an orange triangle with a red border (a slow-moving-vehicle emblem). You should expect that vehicle to:

Answer choices

• Travel at 25 mph or less, so slow down and be patient— Correct answer
• Speed up to match freeway traffic
• Move onto the shoulder so you can pass on the right
• Be signaling that it is safe for you to pass

Why this is the answer

An orange and red triangle on the back of a vehicle marks a slow-moving vehicle, such as road maintenance equipment, which usually travels at 25 mph or less. Adjust your speed and stay back. It does not mean the driver is signaling you to pass, and the vehicle will not speed up to match freeway traffic.
