Vehicles can't just 'stop dead' - they are big and heavy, and if someone steps in front of them the driver may have no chance of stopping in time. Stopping distance depends on the speed of the car click on the above graphic to see an enlargement of it. That is why we have speed limits - the more likely it is for a driver to have to stop, the lower the speed limit.
The car (worn brakes, extra weight, bald tyres etc) Note that for AQA syllabus 4403 the examiners limit 'poor condition of the car' to the car's brakes or tyres.
So, the faster the vehicle is travelling the greater the actual braking distance is compared to the thinking distance by the square of the factor that increased the speed - it is a squared relationship between speed and distance..
Thinking distance is the time the vehicle travels in the reaction time - the time it takes to realise you have to stop! Most driver's education classes teach future drivers that the stopping distance of a skidding car is directly proportional to the square of the speed of the car. This mathematical relationship between initial speed and stopping distance is depicted in the animation below.

Perhaps you learned in a drivers education course of this mathematical relationship between initial speed and stopping distance.
Since the potential energy of the car is the same in the initial state (before braking) as the final state (after stopping), each term can be canceled from the above equation.
The above equation shows that the stopping distance (d) is proportional to the square of the speed (v2). For more information on physical descriptions of motion, visit The Physics Classroom Tutorial.

A road with houses on it normally has a 30mph limit but a motorway has a limit of 70mph because there should be no one trying to cross it.
Let us say the reaction time (time between you realising you need to stop and you actually hitting the brake) is 0.5s.

If you are travelling very fast not only will the vehicle travel a long way before you realise you have to apply the brakes - but the imcreased momentum of the car will mean that the brakes have to be applied for longer to bring the car to a standstill.
It is important that you understand the limitations of your car and your own reactions when you consider the speed you travel at.
This is portrayed in the work-energy bar charts above by the height of the KE bar for each car.
In this case, Theta is 180 degrees since the force of friction and the displacement of the car are in opposite directions. The animation depicts that the stopping distance of the red car is four times (22) that of the green car and the stopping distance of the blue car is nine times (32) that of the green car.
