I am a black woman truck driver in the US. A majority (not all) of the other women I see driving are also black, especially if under 40. Again, just my personal experience.

I can't speak towards all black women truckers, but it's been fine for me; haven't really felt unsafe at all in terms of other truckers. I mostly keep to myself though and I look kind of masculine from afar, so that probably helps. I often stay in rest areas or smaller truck stops instead of always stopping at Loves or Pilot, so that might have something to do with it too. But as long as you trust your gut and keep your wits about you you should be fine, generally speaking.

I would say that the industry mostly sucks to get into, but that goes for anyone--not because of racism (well, not racism directed at black women) or because of safety, but just because of lack of pay and the way most OTR companies treat truckers, especially when it comes to home time and PTO. Plus you don't always have a good place to use the bathroom since shippers and receivers often treat truckers like animals (not all of them, but enough of them), so you have to become really adept at pissing in bottles, even for women.

I know another black woman trucker who works for Crum Trucking though and likes it well enough, so maybe my company is just stingy with time. But they pay decently and the trucks are kept up well. Finding the right company for you can really make or break your career, especially at the start.

Feel free to PM me answer specific questions you might have.
