Road users in the north are being advised to take extra care after the clocks go forward tomorrow.
Police Scotland says that the darker mornings will pose more danger to cyclists.
Inspector Angus Stewart, of the divisional road policing unit, said: “With the mornings becoming darker temporarily, it is important to ensure you are fully visible whether you are driving, cycling, walking or jogging.
“The use of lights and bright reflective clothing are essential to ensure you are seen by road users if you’re out and about at dawn or dusk.
“Low sun can be an issue for drivers so remember to keep sunglasses within easy reach. With the Easter holidays round the corner the volume of road users and pedestrians in towns and villages is likely to rise so it is important to stay alert to pedestrian crossings and adjoining footpaths – especially near to parks and areas where children might play.”
Cyclists should wear high visibility clothing to ensure they can be seen.
