Bill > HB114

This bill, known as Mateo's Law, amends Maryland's transportation law to require individuals involved in a motor vehicle accident that results in death or life-threatening injury to submit to testing for impairment. Previously, such testing was contingent on a police officer having reasonable grounds to believe the driver was impaired by alcohol, drugs, or controlled dangerous substances. Now, if a person is involved in such a serious accident and is detained by a police officer, they will be required to undergo a breath test to determine alcohol concentration and a blood test to check for alcohol, drugs, or controlled dangerous substances, regardless of the officer's initial belief about impairment. This change aims to ensure thorough investigation in severe accident cases. The bill also clarifies that medical personnel performing these tests are protected from civil liability unless their actions amount to gross negligence, and it is set to take effect on October 1, 2026.
