Senator Chuck Schumer is pushing to upgrade safety standards on stretch limos and other motor coaches..

The call comes in the wake of a limo crash on Long Island that killed four women and injured others last month.

The Senator is urging the National Highway Traffic Safety Administration to investigate limo crashes on the ground to determine what might have gone wrong and to make recommendations for safety improvements.

Schumers goals are to make limos safer for passengers and more crash resistant.

Right now he says many limos are lacking features like the necessary number of side airbags, reinforced rollover protection bars, structurally sound frames and accessible emergency exits. Schumer says according to limo industry figures 1 in 4 accidents involving stretch limos are side impacting.
