If you must drive onto the shoulder to avoid a hazard, stay on it until you come to a stop; then signal, check your mirrors, and merge back into traffic. Avoid braking on the shoulder at speeds higher than about 20 mph. To help maintain control, always keep one set of wheels on the pavement, if possible.

Always decrease your speed when traveling through a construction area. Slow down even further if there are workers on or near the roadway.

Always observe posted speed limits for work zones. Slow down if road or weather conditions are adverse, and slow down even more if workers are on or near the road.

If you see a distracted driver, give them plenty of space and maintain a safe following distance.
