At any time of year driving in wet conditions creates extra hazards for the driver, just the same as in ice or snow.  Taking this in to account, it is important to see the reason for this, and how you can adapt your driving to the conditions.  As per any journey pre-drive safety checks are essential to been safe.  “FLOWERY” is a good way of remembering this, these should be done in reverse order, as the most critical check is You and Rubber…

F – Fuel levels
L – Loads, safely secured and not overloaded
O – Oil levels correct
W – Water and fluid levels correct
E – Electrics (including all lights)
R – Rubber  including tyre checks, and good wiper blades.  A good chance to keep windows clear
Y – You – Sober, alert, awake and licensed. 

In the rain, or in standing water scenarios the tyres have less traction with the road.  Stopping distances double as it takes longer much to stop.    The video below demonstrates the limitations of traction.
