DRIVERS have been warned to make sure their windows are completely clear and children urged to wear high visibility clothes.
Darkness is now falling at teatime, but when the clocks go back this weekend night will arrive even earlier.
Road safety officials believe everyone can play a part in keeping people from harm.
The Government's Be Safe Be Seen campaign is targeting children while the RAC is homing in on drivers in a dual-pronged road safety blitz.
More than 900 children were killed or badly hurt on the UK's roads last winter.
A spokesman said: "It is important youngsters are not only seen after dark, but also in bad weather when drivers may not be able to see as clearly.
"For maximum visibility, fluorescent or bright clothing should be worn in the daytime and reflective material should be worn at night."
Calderdale Road Safety Officer Peter Shepherdson said: "Dark evenings and dull winter days lead to an increase in the number of people injured on the roads.
"It is against the law to cycle after dark without a white front light, a red backlight and a red reflector at the back," he added.
"Fluorescent jackets with reflective strips across them also help children to stay visible when out on their bikes in the day or evening."
The RAC said that between October and December last year there were nearly 77,000 people hurt on the UK's roads and almost 230 of them were fatal accidents involving pedestrians and cyclists.
A spokesman for RAC Auto Windscreens said it was vital motorists de-misted all their windows before setting off.
"It takes between eight and 10 minutes to de-ice properly, but this time could save your life and those of others," he said.
"The largest penalty imposed for causing a serious smash is a 10-year prison sentence if your dirty glass leads to death by dangerous driving."
