Truckers rely on pusher to get over Donner Summit
By Tony Bizjak, Sacramento Bee
With drought-defying snowstorms romping through the Sierra on a weekly basis, truckers once again are discovering how tough Interstate 80’s Donner Pass can be.
Commercial trucks carrying 80,000-pound loads are losing traction in the snow, officials say, even with tire chains on, getting stuck in heavy summit traffic, blocking lanes and threatening to close the highway.
That, officials say, is where the pusher truck comes in.
