Police Scotland is advising drivers in Tayside to drive with extra caution following snow fall overnight.
Officers say all routes have been affected, making for hazardous driving conditions.
There have already been a number of collisions reported this morning, particularly on the A90.
Tayside Police Division is asking that drivers:
• Slow down and leave plenty of room to stop. You should allow at least three times more space than usual between you and the car in front.
• Brake gently to avoid skidding. If your wheels lock, ease off the brakes.
• Turn on your lights to increase your visibility to other motorists and always clear all ice and snow off the car windows before setting out.
• Drive slowly on snow in the highest gear possible.
• Do not assume your vehicle can handle all conditions. Even four-wheel drive vehicles can encounter trouble on winter roads.
• Visibility is often reduced because of fog, rain, spray, hail or snow. Remember to ensure that you use dipped headlights in periods of reduced visibility. Fog lights can only be used when visibility is seriously reduced to less than 100 metres but must be switched off if visibility improves.
