Final answer:
The three conditions that must be shown to exist to uphold a charge of reckless driving are operating a vehicle at a significantly higher speed than the speed limit, engaging in aggressive or dangerous behavior on the road, and causing an accident resulting in property damage or injury to others.
Step-by-step explanation:
The three conditions that must be shown to exist to uphold a charge of reckless driving are:
- The driver was operating a vehicle at a speed that was significantly higher than the posted speed limit.
- The driver was engaging in aggressive or dangerous behavior on the road.
- The driver caused an accident resulting in property damage or injury to others.
In the given scenario, Peter's behavior of tapping on his horn, tailgating, and attempting to pass the car at a higher speed would be considered aggressive and dangerous behavior on the road, meeting one of the conditions for reckless driving. However, the other two conditions, such as significantly exceeding the speed limit and causing an accident, are not mentioned in the scenario.
