Authorities are warning Marylanders about the danger heat can cause as temperatures skyrocket across the state. Officials with the Maryland Transportation Authority Police say that temperatures inside of a parked vehicle can be significantly higher than outside. A vehicle without its air conditioning on can reach around 123-degrees if it’s only about 85-degrees outdoors. Drivers should always double check to make sure they don’t leave any children or pets unattended when they leave their vehicle alone.
