An Act known as "Drug Test Consent Bill" aka "Christina's Law"

HD 3539 amends Massachusetts DUI laws to explicitly include impairment from any drug that affects driving ability, not just alcohol or marijuana. It requires drivers arrested for DUI to consent to chemical tests (breath, urine, or blood), with specific protections: blood tests can only be drawn by medical professionals at a treatment facility, and drivers with certain medical conditions (like hemophilia) cannot be forced to provide blood. Refusing a test results in an automatic 180-day license suspension, but evidence of refusal cannot be used against the driver in court. The bill also establishes that a blood alcohol level of 5/100ths or lower creates a legal inference the driver was not impaired, while drivers under 21 face stricter penalties at 2/100ths or higher.
