If you place emergency warning devices four paces behind your truck, forty paces behind your truck, and forty paces in front of your truck, what type of road would you be on?

If you place emergency warning devices four paces behind your truck, forty paces behind your truck, and forty paces in front of your truck, what type of road would you be on?

• A. A two-lane road
• B. A divided highway
• C. A multi-lane highway
• D. Both A and B

Answer: (A)

When you’ve stopped on a roadway, you must place emergency warning devices so drivers in both directions can see the hazard and slow down in time. On a two-lane road, the standard pattern is to place one device very close behind your vehicle, then another about a longer distance behind, and a device in front at a similar long distance. This setup gives drivers behind you a warning quickly, while also signaling oncoming traffic from in front of you. The distances described fit the typical two-lane-road rule: a close-behind device for immediate protection, plus larger-distance devices behind and in front to alert traffic in both directions. Divided highways or roads with medians change how you warn traffic, so the exact front/back placements differ there; the described arrangement matches a two-lane road.
