A new law will soon impact anyone involved in a serious car crash.

Gov. Andrew Cuomo signed a bill on Monday, expanding police officers' responsibilities when investigating accidents that result in a serious injury or death.

When the law goes into effect less than 30 days from now, officers investigating a serious car crash will be required to ask drivers to go through a sobriety test if there are reasonable grounds to suspect the driver broke a law.

If a driver involved in a crash refuses, the DMV could suspend their license.

Previously, drivers were tested at the discretion of the officer on scene.

Just last year, there were more than 5,000 car crashes involving impaired drivers in New York, nearly 500 more compared to 2015.
