Under normal, dry conditions on a level road, a car is travelling at a speed of $40\text{ mph}$ . According to the UK Highway Code, what is the vehicle's braking distance in metres?

Cevap: 24 metres

Cevap

24 metres

According to the UK Highway Code, travelling at

40\text{ mph}

in dry conditions requires a total stopping distance of

36\text{ metres}

(

118\text{ feet}

). This consists of a thinking distance of

12\text{ metres}

(

40\text{ feet}

) and a braking distance of

24\text{ metres}

(

78\text{ feet}

). Therefore, the braking distance alone is

24\text{ metres}

Adım Adım Çözüm

Identify the components of total stopping distance

\text{Stopping Distance} = \text{Thinking Distance} + \text{Braking Distance}

Total stopping distance is split into the distance travelled while reacting and the distance travelled while the brakes are applied.

Recall the official Highway Code standard values for

40\text{ mph}

in dry conditions

\text{Total stopping distance} = 36\text{ metres}

\text{Thinking distance} = 12\text{ metres}

40\text{ mph}

, a driver typically travels

12\text{ metres}

during reaction time and has an overall stopping distance of

36\text{ metres}

Calculate the braking distance component

36\text{ m} - 12\text{ m} = 24\text{ metres}

Subtracting the thinking distance from the total stopping distance yields the vehicle's actual braking distance.
