When it comes to the Onspot automatic snow chain system there are many advantages. Through the simple push of a dashboard switch the chain wheels are engaged providing the driver with traction on snow and ice. It is not necessary for the driver to get out of the vehicle and manually strap chains on the tires. The driver can stay in the cab of the vehicle, avoiding the harsh winter conditions, the dangers of chaining up on the side of the road, and the overall physical exertion associated with conventional chains. This is all well and good for the driver.
