Most commonly a vehicle will be made with tempered glass for its windows except for the windshield. As tempered glass is more prone to shattering, the windshield is usually made from laminated glass, which makes it shatter proof and allows it to withstand more impact. Windshield glass is made laminated so that it prevents the breakage from stones, rocks, and other potentially damaging objects. Laminated glass is essentially just two pieces of thinner tempered glass that are fused to an inner rubber layer.
