Work zones put drivers and road workers side by side. Common crashes there are rear-end collisions from drivers going too fast, hitting fixed objects, and vehicles striking workers. Expect sudden stops, lane shifts and changed road surfaces.

Know the rule

Work zones may be long-term projects with permanent signs or temporary areas set up for just a few hours with portable signs.
