California Adverse Conditions Practice Test 2026

Adverse conditions change how everything on the road behaves, and this topic tests whether you adjust. In rain, fog, or snow you slow down and stretch out your following distance because stopping takes longer. Fog calls for LOW beams, since high beams bounce off the moisture and glare back at you. California also requires your headlights on any time your wipers are running, a rule people forget on a light drizzle day.

Emergencies are where instinct works against you. If you hydroplane, ease off the gas and do not stab the brakes; let the tires find the road again. In a skid, steer gently in the direction you want the car to go rather than fighting the wheel. The mistakes this topic hammers are flipping on high beams in fog and braking hard on a wet or icy surface. Practice free, no account required.
