Dash cams can be used on trucks or RVs, and they are especially popular among truck drivers for safety and insurance purposes. Truck drivers often face challenging driving conditions, such as long hours on the road and the potential for accidents, so having a dashboard camera can provide valuable evidence in the event of an incident. Dash cams can also help truckers monitor their cargo and ensure that it is secure during transport. Similarly, RV drivers can benefit from using these cameras to capture their adventures on the road and to provide evidence in the event of accidents or incidents.
