The first rainfall means that the roads will be particularly slippy as the water lays on top of an accumulation of dust and dirt on the roads. Take extra care when driving. Slow down, make gentle movements and take it easy.
Use your headlights, keep your speed well under control and low and keep a safe distance from the vehicle in front, remembering that stopping distances are increased on wet roads.
Keep an eye on the road surface and look for colour changes. The appearance of brown in the water could indicate mud or dirt, if the water looks multicoloured and has a rainbow effect, it could indicate oil mixed with the water.
Remember, slow, gentle movements, and take it easy.
