Winter braking distance
In winter a car needs a much longer distance to stop on snow and ice. Check how fast you brake when your phone pings, whether your following distance is enough, and whether your tyres are still good for winter.

How fast do you brake when your phone pings?
A message arrives just as the car ahead brakes. Press as soon as the brake lights come on. One try.

Is your following distance enough for winter?

Will you spot a pedestrian in the dark?
In winter it gets dark early and a pedestrian steps onto the road unexpectedly. Press as soon as you see them.
4 / 4
Are your tyres still good for winter?
Enter the last 4 digits of the DOT code on the tyre sidewall and the tread depth. You will see the tyre's age and how much longer the braking distance is on snow.
The digits are in an oval frame after the letters DOT. The first two are the week, the last two the year: 2319 = week 23 of 2019.
Enter the digits to see the tyre age right away.
