Sussex is moving from summer to autumn - and drivers need to make sure they are ready for it, according to Sussex Police.
The force says the change in weather conditions has left the county’s roads far more difficult to control a vehicle on if motorists are not prepared.
Through the dry summer roads in Sussex have absorbed dust and engine oil that have left them covered by a film of dirt that has not yet been washed away.
When it rains, or even when there is dampness in the air, the roads will be greasy to drive on.
In addition, the sun is lower in the sky than in the summer, meaning drivers are more likely to be dazzled by its brightness or by glare off the roads.
Senior forensic collision investigator Colin O’Neill from Sussex Police said, “Conditions have changed.
“The roads might look the same as last month but they are different to drive on.
“The greasy conditions mean extra care is needed when braking or cornering in particular.
“Don’t assume you will have the same levels of grip on the roads - you might not have.”
Inspector Carl Knapp, from the Sussex Police road policing unit, said, “Now is the time to check the tread on your tyres.
“You need all the grip you can get in these conditions so if they are getting close to the safe limit get them replaced now.
“Drive more slowly, take care on the slippery roads and be prepared to stop if you cannot see ahead safely because of the sun.
“Please take extra care and make sure you complete your journey safely.
“It’s better to be a few minutes late than end up in hospital.”
