50,000 trucks come through Oklahoma each day, at the crossroads of America, leaders in the trucking industry say crashes are becoming less common.
"Our accident frequency has basically been going down the last 10 years," said Dan Case, Executive Director of Oklahoma Trucking Association.
Less accidents are a sign of progress, after three major accidents in the past week, safety questions are being raised.
"Maintenance, equipment, and training are necessary for safe," said Capt. George Brown, of Oklahoma Highway Patrol.
Weigh station often help with trucking.
"There are all kinds of rules and regulations they have to follow to move through the state or within the state," said Case.
Officials say due to funding problems, it is taking a while to bring these weigh stations up to date, and there is not enough money to keep them open 24 hours a day, seven days a week. Until then, OHP advises all drivers to be extra careful.
"Our message is allow them plenty of room," said Capt. Brown.
Leaders with the Oklahoma trucking Association say this is especially important on interstates. They say it takes 110 yards for an 18 wheeler to stop correctly at 70 mph, and drivers need to bear that in mind when they share the road.
"That truck can't stop on a dime like a lot of other cars," said Case.
