Truck reflective tape is the best way for a person to be sure his or her truck is safe in terms of other people seeing it. This is because even the smallest amount of light will reflect from the tape, showing walkers, bikers, and other drivers that the vehicle is there. This is especially important at night time or when the weather is bad.
Putting reflective tape in strategic places on your truck such as the front and back bumper, and side sides of the bed and doors is a good start. You can also have professionally installed siding tape put on at some stores, which does not come off and never needs to be changed. However, you need to always make sure the tape is clear of debris so that people can see you coming, or see if you are parked.
