Around 20% of the truck drivers are foreigners and many of them do not read or speak English. Add in all of the other illegals driving in our country and you have millions of people driving that cannot read or understand traffic signs or instructions. How many people die from accidents caused by this? How much more do citizens pay for insurance as a result of this? One of many reasons we need to deport all of the illegals. Can you imagine driving around Saudi Arabia with no GPS trying to get from one place to another by reading their traffic signs?
