My truck was parked on a slight slope in my driveway. I got in to move the truck to my normal parking space. When I started the truck I noticed the emergency brake was on. I put the truck into drive- the truck accelerated with my foot on the brake. The truck struck the corner of my deck and didn't stop until I hit the corner at my house. I had the brake pushed to the firewall and the truck would kept accelerating. Thankfully the airbags did not deploy. Significant damage was done to my house and my truck.
