Dead ground is used to describe a part of the road that you are unable to see completely. For example, an area of dead ground may be where there is a large dip in the road which prevents you from seeing the road fully.
How to drive safely when approaching dead ground?
When you come across an area of dead ground, you should check your mirrors, release the gas and apply defensive driving by thinking 'what if?'.
Try to think of the worst possible hazard that could realistically be in the area of dead ground and prepare yourself for this potential hazard.
For example, there could be a broken-down car or a large dead animal in the road. Act accordingly to this potential hazard by applying the MSPSL routine on the approach.
