Final answer:
Approaching a stop or turn requires signaling at least 100 feet prior and adjusting distance based on speed and conditions. Stopping distance varies with speed, reaction time, and road conditions, requiring more space on wet pavement. Safety is enhanced by leaving several car-lengths of buffer space when crossing a street.
Step-by-step explanation:
When approaching a turn or stop, it is important to begin slowing down well in advance. The distance to slow down before a stop or turn can be influenced by various factors including vehicle speed, road conditions, and driver reaction time. Generally, you should signal your intention to turn at least 100 feet before the turn, which allows other drivers and pedestrians to anticipate your action. However, this distance can increase if you're driving at a higher speed or in poor road conditions.
When it comes to stopping, it is also crucial to consider the vehicle's braking distance in addition to driver reaction time. The figure presented indicates that for a car traveling at 30.0 m/s, with a 0.500 second driver reaction time, the distance required to come to a full stop varies notably between dry and wet pavement. Thus, allowing for adequate space based on these conditions is essential for safety.
Drive Safely by Accounting for Stopping Distance
To safely cross a street assuming vehicles are not speeding, one should consider the distance necessary for a car to stop, depending on the road conditions and typical stopping distances for the speed at which vehicles are traveling. It might be advisable to allow a distance equivalent to several car-lengths as a buffer before crossing. This gives you and the approaching vehicles ample time to react and stop if necessary.
