If you have a road emergency and must park on the shoulder, how soon should you put out your triangles?

Answer: B — 10 min.

It is important to put out your triangles as soon as possible when you have a road emergency. Option A (5 minutes) may not provide enough time for other drivers to slow down and avoid hitting your vehicle. Option D (30 minutes) is too long of a delay and can put you and other drivers at risk. Option C (15 minutes) is also a long time and can be dangerous. Option B (10 minutes) is a reasonable amount of time to put out your triangles and will give other drivers enough warning to avoid your vehicle.
