We’ve all driven when we have been tired. Maybe you had a long, exhausting day and you are just trying to get home, or perhaps you did not sleep well the night before and thus you are still tired when you awake to start your day. Regardless of the cause, know that driving when tired can lead to serious consequences and that you need to take precautions against this.
