A wrecker driver provides roadside assistance to motorists. Your duties and responsibilities are to tow wrecked or disabled vehicles, change flat tires, jump start cars with dead batteries, and unlock doors when the driver has left the keys inside. You may also assist with simple repairs. When a vehicle needs to be towed or left on the road, you drive the passengers to your shop. In addition to these duties, you are responsible for maintaining your truck and equipment, filing reports and logs, and filling out customer invoices.
