Final answer:
You should stop at least one car length or approximately 20 feet from the crosswalk on a multilane road when stopping for pedestrians, ensuring both their safety and visibility to other drivers.
Step-by-step explanation:
When you stop for a pedestrian in a crosswalk on a multilane road, you should stop at a distance that ensures the safety of the pedestrian and provides enough room for other drivers to recognize the situation and react accordingly. It is generally advised to stop at a minimum of one car length or approximately 20 feet from the crosswalk to allow other drivers to see the stopped pedestrian ahead and to give the pedestrian a clear path to cross safely. It's important to always follow local traffic laws and regulations as they can vary by location.
