The Maryland State Police, in cooperation with Saint-Gobain Vitrage and the Insurance Institute for Highway Safety, installed anti-lacerative Securiflex Inner Guard windshields in a number of their new vehicles. The exposure and visibility characteristics of these windshields have been monitored and compared to the experience of standard HPR windshields of similar vehicles in the fleet. The performance of the Securiflex windshields has shown visibility properties similar to standard windshields. More importantly, the superior safety characteristics of the Securiflex windshield prevented a Maryland State trooper from recieving lacerative injuries as the result of a collision in which his vehicle struck the rear of another vehicle. The National Highway Traffic Safety Administration (NHTSA) has estimated that anti-lacerative windshields such as the Securiflex windshield could eliminate over 170,000 lacerative injuries each year resulting in an annual medical cost savings of over $10 million.
