What is the minimum distance a vehicle's turn signals must be activated before turning at lower speed limits?

Answer: C — 100 feet

The minimum distance that a vehicle's turn signals must be activated before turning at lower speed limits is 100 feet. This rule is established to ensure clear communication between drivers on the road. Activating the turn signals 100 feet prior to the turn gives sufficient warning to other road users, allowing them to react appropriately, which helps in maintaining safety and reducing the likelihood of accidents. At lower speed limits, a shorter distance may not provide adequate time for surrounding drivers to perceive the signal and adjust their speed or position accordingly. Therefore, this regulation is set to enhance predictability in driving behaviors, contributing to overall road safety.
