Rules and conditions
Signal about 100 feet before a turn while still checking for conflicting road users. The signal communicates a planned maneuver; it does not grant priority or replace observation. When turning right, enter a permitted bicycle lane only within 200 feet of the turn and after checking for bicyclists. The limited approach allowance does not make a bicycle lane a general driving lane. If a turn is missed, continue until a safe and legal opportunity to change route appears. A route error is less dangerous than a last-second lane change or abrupt stop.
Worked comparison
For example, a driver plans a right turn at the next intersection. The defensible response is: Signal early and check for conflicts. Compare this with the mistaken proposal: Signal only after beginning the turn. The signal communicates a planned maneuver; it does not grant priority or replace observation. For example, a right turn is approaching beside a bicycle lane. The defensible response is: Check bicyclists; enter within 200 feet of turning. Compare this with the mistaken proposal: Drive in the bicycle lane for the entire block whenever convenient. The limited approach allowance does not make a bicycle lane a general driving lane.
Transfer and self-check
Review the sequence signal, mirrors, blind area, position, speed, and yielding. Explain why a last-second route instruction does not justify a sudden lane crossing. For a bicycle-lane approach, include both the permitted distance and the cyclist check.
A driver plans a right turn at the next intersection. Which response follows the applicable California handbook rule?
- Identify the relevant condition: A driver plans a right turn at the next intersection.
- Signal about 100 feet before a turn while still checking for conflicting road users.
- The signal communicates a planned maneuver; it does not grant priority or replace observation.
Compare the other answer choices
The proposal "Signal only after beginning the turn." conflicts with this applicable condition: Signal about 100 feet before a turn while still checking for conflicting road users. It does not resolve the stated risk: The signal communicates a planned maneuver; it does not grant priority or replace observation.
The proposal "Assume signaling obligates cyclists and pedestrians to stop." conflicts with this applicable condition: Signal about 100 feet before a turn while still checking for conflicting road users. It does not resolve the stated risk: The signal communicates a planned maneuver; it does not grant priority or replace observation.
The proposal "Omit a signal when the destination is familiar." conflicts with this applicable condition: Signal about 100 feet before a turn while still checking for conflicting road users. It does not resolve the stated risk: The signal communicates a planned maneuver; it does not grant priority or replace observation.
