Remember the Taillights
Most modern cars today are equipped with automatic daytime running lights. This means the front lights switch on automatically — but in many cases, the rear lights do not. This is especially true for micro and mini cars, where you often have to manually turn on the taillights.
Larger vehicles often have a light sensor that activates the dipped headlights (and taillights) when it gets dark. However, these sensors don’t always detect fog or overcast weather, meaning your taillights may remain off — making your car nearly invisible from behind.
Since July 2016, all new cars are required to automatically turn on dipped headlights (including taillights) in low visibility conditions.
Does your car turn on the taillights automatically in fog, rain, or darkness?
If not — and you tend to forget switching them on manually — consider having the car re-coded.
FDM recommends configuring your vehicle so that the taillights switch on together with the daytime running lights. In many vehicles, this can be done easily through a software update or re-coding.
If you're buying a new car, FDM advises you to have it written into the purchase agreement that the car is delivered with this adjustment made.
Keep a Safe Distance
Most accidents happen because of insufficient distance to the vehicle in front.
As a rule of thumb, always keep a minimum two-second gap — or half your speed in meters:
At 40 km/h → Keep at least 20 meters
At 120 km/h (motorway) → Keep at least 60 meters
