Final answer:
Drivers in speed zones of 45 mph or less should signal at least 100 feet before turning to alert others on the road. This helps to prevent accidents and encourages adherence to traffic signals designed to control speed.
Step-by-step explanation:
When driving in speed zones of 45 mph or less, it is important to signal continuously during the recommended distance before making a turn. While specific distances may vary by jurisdiction, a common rule is to signal at least 100 feet before turning. This rule is in place to ensure that other drivers and pedestrians are aware of your intentions to turn, thereby reducing the risk of accidents. Proper signaling coupled with adherence to the speed limit contributes to safer intersections where vehicles are less likely to speed through without regard to traffic controls like signals, which are designed to make vehicles slow down and proceed with caution.
