LEARN BEFORE YOU DRIVE

How does speed affect reaction and stopping?

Passenger → Traffic Reader → Decision Maker

QUICK ANSWER

As speed increases, traffic situations develop faster and the distance required to stop increases.

WHAT THAT MEANS

Safe speed depends on both the posted limit and the actual conditions you can see and control.

SUPPORTING ANSWER SECTIONS

Reaction time
The vehicle keeps moving while the driver recognizes and begins responding.

Braking distance
More speed generally means more distance is needed to slow or stop.

Conditions
Curves, darkness, weather, and limited visibility can require slower travel.

DRIVEx WAY OF THINKING

Ask: At this speed, how much time do I have to notice, decide, and stop?

WATCH
KEY TAKEAWAYS

• Speed changes decision time.
• Faster travel needs more space.
• Conditions can require slower speed.
• Do not treat the limit as a target in every condition.

YOU MAY ALSO BE WONDERING

Why slow before curves?

Curves reduce sight distance and require controlled steering and speed.

Why slow in bad weather?

Traction and visibility can be reduced.

How does darkness affect speed?

Do not drive faster than available visibility and stopping ability can safely support.

How does speed affect following distance?

Higher speed increases the time and space needed between vehicles.
