RTT Speed, Stopping Distances & Following Distance 3

Question 1

What does the 'two-second rule' measure?

Accepted Answer

The minimum gap in time between your motorcycle and the vehicle ahead

Answer

The two-second rule measures the time gap between your front wheel and the rear of the vehicle ahead, ensuring enough space to stop if that vehicle brakes suddenly.

Question 2

Under what condition should a motorcyclist use a four-second following distance?

Accepted Answer

When riding at night, in poor weather, or on slippery surfaces

Answer

Night riding, rain, or slippery roads all reduce traction and visibility, making a four-second gap necessary for a safe reaction margin.

Question 3

If you are riding at 60 mph and need to stop for a hazard that appears 200 feet ahead, what is likely to happen?

Accepted Answer

You will likely be unable to stop in time because total stopping distance exceeds 200 feet

Answer

At 60 mph total stopping distance is approximately 240 feet under ideal conditions, so 200 feet is not enough space to avoid the hazard.

Question 4

How does excessive speed affect a rider's ability to steer around an obstacle?

Accepted Answer

Higher speed requires a larger radius to steer around an obstacle, making avoidance harder

Answer

At higher speeds, physics requires a wider arc to change direction, so the space needed to steer around an obstacle increases significantly with speed.

Question 5

What is the effect of worn or underinflated tires on stopping distance?

Accepted Answer

Stopping distance increases because the tires cannot generate maximum grip

Answer

Both worn tread and low pressure reduce the tire's ability to grip the road, extending the distance required to stop.
