The RSA is also advising vulnerable road-users such as pedestrians, motorcyclists and cyclists to ensure they are clearly visible to other road-users by wearing high visibility clothing and using lights.
Other tips for road users include:
• Switch on dipped headlights and fog lamps if visibility is reduced
• As you enter fog, check your mirrors and slow down. Use your foot brake lightly so that your lights warn following drivers.
• Do not drive on the tail-lights of the vehicle in front (Target Fixing). This can give a false sense of security and you will be too close to be able to brake safely.
Gardaí and @RSAIreland are warning road users of the dangers posed by travelling in fog following a weather warning issued today. Check your car is in good working order, slow down and use appropriate lights. For further info: https://t.co/oeK5e4khYg https://t.co/1gH5QJ3yBh
