East Sussex Fire and Rescue Service issued a safety warning ahead of a 24-hour strike by the Fire Brigades Union.
Firefighters announced a further 24 hour strike to take place from 9am today (December 9).
The strike is following a three-year dispute over pensions with the government.
During the 24 hour strike, East Sussex Fire Service said contingency crews will be on duty but there will be reduced levels of cover. It asked the public to do what they can to reduce the need to call 999.
A fire service spokesman said, “Roads can quickly become more treacherous during the winter.
“Make sure you are prepared by checking your vehicle is roadworthy. Tyres, windscreen wipers and lights should all be in good condition – replace anything which isn’t working.
“Remember to slow down and keep your distance from the car in front of you - it takes much longer to stop in the wet and fallen leaves can be just as slippery and treacherous for motorists as driving on ice.
“If your vehicle loses its grip, or “aquaplanes” on surface water take your foot off the accelerator to slow down. Don’t brake or steer suddenly because you have no control of the steering or brakes.
“During extreme weather, we prioritise calls where lives may be at risk through a risk of fire or other emergencies.
“For example when flood water is affecting electrics in buildings, where a building or structure has become dangerous to passers-by or when there has been a road traffic collision.
“Where lives are not at immediate risk, a number of other organisations may be better placed to help.”
