Hot Cars Act of 2021
This bill requires safety measures in passenger cars to reduce injuries or deaths from heatstroke and other harms to occupants of unattended vehicles.
Specifically, the National Highway Traffic Safety Administration (NHTSA) must issue a motor vehicle safety standard that requires certain new passenger motor vehicles to include a system that detects and warns of the presence of an unattended occupant in the passenger compartment. The NHTSA must issue the final rule prescribing the safety standard within two years after the enactment of this bill, with full compliance with the standard required not later than two years after the rule is issued.
After the standard is issued, the Department of Transportation must periodically contract with an independent third party to study retrofitting passenger motor vehicles with technologies and products that detect and warn when there is an unattended occupant in the passenger compartment. The study must identify relevant technologies and products to retrofit vehicles and provide recommendations about testing such technologies and products. Information about the performance of the technologies and products must be published on the NHTSA's website.
To require the Secretary of Transportation to issue a rule that 
 requires all new passenger motor vehicles to be equipped with a child 
              safety alert system, and for other purposes.

    Be it enacted by the Senate and House of Representatives of the 
United States of America in Congress assembled,

SECTION 1. SHORT TITLE.

    This Act may be cited as the ``Hot Cars Act of 2021''.

SEC. 2. FINDINGS AND PURPOSE.

    (a) Findings.--Congress finds the following:
            (1) Children and pets left unattended in vehicles, or 
        children independently accessing unoccupied vehicles, are a 
        significant public health and safety problem.
            (2) Millions of children are transported every day in the 
        back seat of vehicles and are at risk of being unknowingly left 
        behind and dying or suffering serious injuries from heatstroke.
            (3) Data collected by KidsAndCars.org found information 
        about at least 8,000 children left alone in hot cars or as a 
        result of gaining access independently into unoccupied cars 
        between 1990 and 2020. Of those, over 990 children have been 
        killed due to heatstroke and more than 1,200 children were 
        injured.
            (4) Over the past 30 years, child hot car deaths have 
        continued to trend upwards despite widespread education 
        programs and public awareness.
            (5) Inexpensive technology is currently available to detect 
        the presence of an occupant unattended in a vehicle and engage 
        a warning.
    (b) Purpose.--The purpose of this Act is to reduce the deaths and 
injuries that result from occupants being left unattended in vehicles 
and instances in which children independently access an unoccupied 
vehicle.

pounds or less to be equipped with a system that detects the presence 
of an unattended occupant in the passenger compartment of the vehicle 
and engages a warning to reduce death and injury resulting from 
vehicular heatstroke, particularly incidents involving children.
    ``(c) Limitation on Capability of Being Disabled.--The motor 
vehicle safety standard prescribed under subsection (b) shall require
