Drivers of Big-Rigs - Semi Trucks, 18-Wheelers...

Have you noticed an increase in Close calls or Road Rage incidents from passing motorists or other big trucks since operating a big rig with a speed governor setting that is set 15 to 20% BELOW the legal speed limit?

On the Freeway, Do you frequently find yourself driving along side another 40 ton big rig with a similar speed governor setting for 5 or 10 minutes when trying to pass?

When you are driving on 2-lane highways, have you noticed large numbers of cars and big trucks lining up behind your big rig, impatiently waiting to pass?

When 15 to 20 vehicles are lined up behind your truck waiting to pass it becomes a potentially dangerous and deadly situation that causes impatient motorists to take chances when passing, some don't make it... Road rage incidents can also occur.

The Safest Highways are the ones where ALL vehicles travel at the same speed. Common Sense tells us this is especially true on 2 lane highways as well as Freeways.

If you answered YES to any of the questions listed above, you may want to consider Speeding Up your Truck to satisfy Safety Concerns....

SafetyPass Pro Customer Comments:

"Thanks for a great product that works and is well made. It saves me between one and two hours per day by just staying close to the speed limit."

"When a company turns down a truck so low that you dread going to work, it's time to find a new line of work or do something about it. I have more than twenty five years driving experience with over three million miles and no accidents.

"After turning down the truck, my close calls more than doubled."

"Turning down a truck looks good on paper, but it creates more problems than it solves. For any drivers still thinking about getting a safetypass pro. It works very well, and the time you save... It will pay for itself in a week. The stress and aggravation you save is priceless."
