Passing target: 20/25 correct (TLA practice target)
Weather, Visibility & EmergenciesStandalone practice
Rain begins and the pavement becomes slick. What is the safest adjustment?
Correct answer: Slow down and leave more space.
Why
Slow down and use smooth steering, acceleration and braking on wet roads. Increase following space and avoid cruise control on slippery surfaces. Sudden inputs can make tires lose traction; a posted maximum is not a promise that the speed is safe in rain.
