Why “15 Minutes” Fails

Physiological heatstroke begins before the current legal limit of criminal negligence is reached.

The 10-Minute Threshold

Within 10 minutes, a car’s interior rises about 20 degrees Fahrenheit. A child’s body warms 3-5x faster than an adult’s. At this point, hyperthermia begins.

The Argument: States with strict 'Zero Tolerance' laws generally see fewer fatalities. Florida allows the longest time (15 mins) and suffers the second-highest death toll in the nation.
