Why should you take care to avoid spillage when refuelling a vehicle fitted with a diesel engine?

Explanation: The diesel you use to run a vehicle is a form of oil and, as such, is very slippery when spilt on the road. The usual places to find diesel spillage are near filling stations and on bends or roundabouts. Overfilled fuel tanks and poorly fitting or missing fuel filler caps are often the cause of diesel spillage, so make sure you replace your fuel filler cap securely after refuelling.
