California DMV Traffic School Practice Test 2026 – Complete Study Guide

When you can’t safely change lanes to give space to a stationary emergency or service vehicle with flashing lights, the smart and required move is to slow down to a safe speed and pass with caution. The idea is to create a safer buffer around workers and equipment, reducing the chance of a crash if a driver or passenger suddenly steps into the roadway or a vehicle moves. Slowing down keeps you in your lane and minimizes the risk of a collision with the stopped vehicle or with workers who may be near the roadway.

Moving into the next lane anyway isn’t safe if the lane change can’t be done without risk, and stopping in your lane can cause rear-end crashes and blocks traffic. Ignoring the vehicle is dangerous and illegal.
