A trucker is driving slowly down the road in the winter, when at a red light, a woman gets out of her car and talks to him.
“Excuse me, sir, you are spilling your cargo.”
The woman gets back in her car, and when the light turns green, the driver keeps trucking.
At the next red light, the woman gets out of her car and says again, “Excuse me sir, you are spilling your cargo.”
Greenlight, the trucker keeps driving.
The third red light, the woman gets out, and before she can repeat herself, the trucker says “Excuse me, ma’am, I am driving a salt truck in Ontario!”
