Some police cars in foreign countries are equipped with various armoured packages to prevent bullets and explosive devices from damaging the car so that the Police officers are safe. Police cars have their windows, windscreen and doors adequately protected against armour piercing bullets, gun fire from hand guns and rifles, explosive devices, etc. Bullet-proofing cars will ensure maximum security for the police officers when they are in the line of fire. Many police cars also come with run flat tires, especially the bigger SUVs that can easily blow a tire under gunfire. This allows the police officers to pursue suspects with all their tires intact.
