Stopping, breaking and thinking distances

Notes on the key points for stopiing distances

HideShow resource information

Stopping distance

  • Distance covered in the time between seeing a hazard and stopping
  • thinking distance + breaking distance
1 of 3

Thinking distance

  • distance the car travels between seeing a hazard and applying the breaks.
  • affected by:

                            - how fast you're going (faster you go the greater the thinking distance)

                            - slow drivers reactions (tiredness, drugs, alcohol, old age)

Braking distance

  • distance travelled whilst breaks are being applyed
  • affected by:

            -how fast you're going

            - mass of car (heavy cars take longer to stop)

            - quality of breaks

            - less friction between road and tyres due to:

                        - road surface

                        -weather conditions

                        -tire quality
