Tom Camp, 73, who has driven an estimated 800,000 to 900,000 miles in the company's signature brown delivery trucks in Detroit and the surrounding area since 1962, reached the 51-year milestone and surpassed an Ohio UPS driver who retired in 2012 after 50 accident-free years on the job, the Detroit Free Press reported Monday.
"We have a notion of a fair's day work for a fair's day pay -- he is worth every penny, and so are the other drivers like him," UPS spokesman Dan McMackin said. "He is one-of-a-kind. He's the pinnacle."
The company said 6,486 drivers of the 65,000 total in the United States have been awarded plaques and a spot in the UPS Circle of Honor for driving 25 years or more without a collision.
Camp said the secret is merely careful driving habits.
"Stay focused," he said. "Stay focused out there and drive defensively. And leave enough space."
Camp said he has never cursed out another driver or made a rude gesture while behind the wheel.
"I'd like to say no," he said. "You might say something under your breath. You don't know who you might be talking to. It might be Mike Tyson or something."
Camp said he has no plans to retire.
"I'd be bored -- too much free time," he said.
