Paint won’t protect. Physical infrastructure is needed for safety in high-speed environments. 

Flexible road safety median barriers are installed along the centre of the road to prevent head-on crashes, which are one of the most common types of fatal crash. They work by absorbing the energy of the impact when a vehicle hits them, slowing it down and keeping it away from opposing traffic. This can reduce the number of people killed or seriously injured in crashes by up to 75%.
