What should you do if you miss your highway exit?

Answer: D — Do not back up; continue to the next exit safely

Missing an exit means you should keep going to the next exit and re-enter the roadway safely, rather than trying to back up or turn around on the highway. Backing up on a freeway is extremely dangerous because other drivers may not expect sudden movement, increasing the risk of a crash. The emergency lane is for real emergencies only and using it to stop or maneuver can block responders and create a new hazard. U-turns on freeways aren’t feasible and are often illegal, as there are no intersections to safely make that turn. By continuing to the next exit, you maintain safe speeds, give yourself space to merge onto the correct ramp, and then chart a safe route back without putting yourself or others at risk.
