In a dense fog, the driver cannot see beyond his own vehicle’s limits. In such conditions driving can prove to be quite challenging unless proper precautions are taken," Delhi Traffic Police Inspector Manju Singh explains. [...] Keeping a sensible amount of space between you and the vehicle ahead is a very good idea. This gives one enough time to react, slow down and stop when required. Pile-ups are often caused when vehicles are following each other too closely and are unable to react when things start to go wrong.
