What should you do before changing lanes on a multilane highway?

Correct answer: D – Check the mirrors and look over your shoulder for vehicles in the blind spot
Before leaving a lane, signal and check traffic in front, behind, and beside your vehicle. Use the mirrors and glance over the appropriate shoulder to check the blind spot. Vermont law requires a driver to ascertain that a lane movement can be made safely before beginning it.
