Image of two hands on a car steering wheelSince the early 1960s the phrase “Drive Defensively” has been taught in driver education courses across America. It means the skill to drive a vehicle safely despite any conditions you encounter and the actions of others. In a typical defensive driving course, students learn crucial crash prevention techniques that include:

  • Scanning the roadway ahead and adapting accordingly to your surroundings
  • Expecting the unexpected
  • Being alert and distraction free
  • Employing the two-second rule for following distances
  • Knowing your vehicle’s stopping distance
  • Being aware of reaction distance
  • Looking through a turn to know what you’ll encounter
  • Preparing for environment hazards and vehicle emergencies
  • Driving with the commitment to be the safest driver on the road

Why Use and How to Choose Pepper Spray

If you carry a gun for self-defense, you should also carry pepper spray.* Even if you don’t carry a gun, you should carry pepper spray, also known as oleoresin capsicum (“OC”).

Using a firearm for self-defense is always the very last option in a lethal attack situation. But you shouldn’t rely solely on a gun as your only means of self-defense. FBI/DOJ crime statistics tell us we’re 5 times more likely to be faced with a non-deadly threat, against which only non-deadly defensive force is legally appropriate, than we are a deadly threat.

Under what circumstances is the use of pepper spray as a defensive tool lawful and advisable? What conditions have to be met before you can use pepper spray in self-defense? Pepper spray is a non-deadly form of self-defense and can be used to stop any reasonably perceived threat of non-deadly harm, which means almost any degree of harm. So long as you use it defensively and not offensively, generally speaking you should be within your rights.

In the following video, Chris Baker of Lucky Gunner says, “OC gives you a force option that’s somewhere between harsh language and shooting somebody. We all know that statistically, we are very unlikely to end up in a situation where we need to use our firearm to defend our life. Much more common are situations that call for some kind of intervention that’s less than deadly force. Maybe someone is behaving in a threatening way, but they don’t have a weapon and they have not done anything yet that would warrant using deadly force. That might be a good time to deploy some OC.
