@Milajoy They have to be able to read the road signs. That has been the cause of several big rig fatalities. Also, truckers talk to each other on CB channels, passing road inform.
@ProudElephant It was that way when I was young. Polling places were set up in people’s garages, dens, by paid volunteers. We had to sign our names in a big book next to our address, show our drivers license to verify signature. The address was also verified at that time. It was easy, and safe.
