Police are launching a new drive aimed at encouraging motorists to put the brakes on fast driving.
Officers across Scotland will take part in the anti-speeding push
This year's slow-down campaign is on April Fool's Day to coincide with the Foolspeed campaign - aimed at curbing fast drivers.
No Speeding Day will target crash sites throughout the country.
The clampdown comes the day after the AA motoring organisation stepped up its
criticism of cameras designed to trap drivers using Aberdeen bus lanes.
Warnings to road users to watch their speed are being led by Lothian and Borders Assistant Chief Constable Ian Dickinson.
He said: "For one day just think about the friends and relatives of those who have had their lives ruined through their loved ones dying on our roads. Help us to make a difference and don't speed.
"The encouraging news is that fatal and serious injuries numbers have consistently fallen over the last few decades in Scotland.
"This can be put down to several factors like improved car design, traffic calming measures, road safety cameras, traffic campaigns and better medical care.
"The success of any road safety campaign most importantly relies on the support of the public and motorists to drive in a safe and responsible manner."
Officers stress that motorists should remember to take extra care when driving near schools, shopping areas and playgrounds.
Mr Dickinson added: "Speed limits are not targets and motorists must always drive or ride at the safest speed for the existing road and traffic conditions.
"Motorists should take a responsible attitude when it comes to their use of speed. Everyone can make a real difference and I urge motorists to join the police in making our roads safer for everyone to use," he said.
As many as 1,894 drivers - one every minute - were caught during a similar campaign last year.
