The RHA Daily Defect App is a free app for LGV/HGV drivers. It allows you to keep a track of any vehicle you may be carrying. This is important for a number of reasons, not the least of which is the fact that many different types of goods are transported in vehicles. This means that it is often difficult to know what is the correct vehicle to use in order to transport the specific goods you are carrying. This is also a problem when it comes to the transport of hazardous goods, such as those that are flammable, explosive, poisonous or otherwise dangerous. This is why the RHA Daily Defect App is such a useful tool. It allows you to make sure that the vehicle you are using is safe to drive.
