The difference between a professional driver and a "trucker".

I've been a professional truck driver since April 1977 after receiving an Honorable Discharge from the US Navy that began near the end of the Vietnam War. My driving record has remained clean my entire career (over five million safe miles). My car insurance is only about $250 twice a year. My goal at work is never about counting miles. It is delivering loads safely (and getting paid every Friday I'm financially secure and living a good life. Will be retiring in 2025 after a 48 year career with a lot of good memories.

The Professional Driver
Professional drivers pre-trip their trucks every day. They follow speed limits (no faster than the maximum limit). They know that driving 5 mph over was never allowed and a fine of about $100 (depending on the state) and points if going 2 to 5 mph over can be enforced. That the speed on ramps is for cars. Your speed limit is half of the posted speed to a maximum of 10 mph under. The heavy weight in a dry van, refrigerated trailer shipping container or normal height flatbed is several feet above the ground to as high as 13 feet. This mean that your load is usually top heavy. Taking turns too fast will result in a turnover. If you feel your cab leaning to the left or right, that is a warning that the top heavy and much heavier trailer behind you in leaning much more.

Driving in construction areas and small towns have a speed limit designed for safe travel through the area. This speed also shows your respect for the highway workers and residents in these towns.

When on the shoulder and going back to the highway. Stay on the shoulder with your four-way flashers on. Gain to a speed of 40 mph while on the shoulder (this lane is wider than your truck so you can safely drive in it). When your speed has reached 40 mph, turn on your left turn signal and slowly merge to the travel lane when it is safe. Turn off your turn signal, but let the four way flashers stay on until your truck is moving at 50 mph. This advanced maneuver also shows your respect to the other motorists and I have received many waves and raves over the CB.

When accelerating do it slowly. My throttle is only down about on third of the way when I upshift (automated transmission). There is no rush and a heavy throttle won't get you there any faster.

Truckers
Truckers put making money their highest priority. "I need my miles and nothing else matters."

Speed limit 55, 60, 65? I'm going 70 or more with my throttle wide open.
Construction zone? Throttle wide open!
Heavy traffic? Ride the left lane and tailgate cars until they get out of my way!
Small town? 25 mph? No way, I'm going 50 or more!
Need to leave the shoulder? Get in the travel lane now. Don't care if the traffic is going 70. I'm cutting them off from a standstill.
Speeding or reckless driving tickets? Getting them at least once a year is normal.
Need more miles and to drive even faster to pay all of these added fines and insurance hikes.
My speed over the limit? Doesn't matter if I'm not caught.
Getting old and need to retire? No way, I need my miles and driving until I die!

As a new driver you have to decide if you want to be a professional driver your entire career and provide for your family or cut the corners and pay the price as a "trucker".
