• Vehicle-concrete safety barrier (CSB) crash analyses were performed using finite element models.
• Rubber-CSB coefficient of friction was experimentally measured for aged and new blocks.
• Vehicle tyres-CSB coefficient of friction has a significant impact on a vehicle rollover.
• Vehicles with a higher centre of gravity are prone to rollover upon collision with common CSBs.
