should elderly drivers have to undergo test to renew licence

First of all you have to define elderly. The younger you are the younger elderly looks to you. As long as they have a good driving record why should they be treated any different than anyone else. They are certainly safer drivers than a lot of young people. To single them out because they have reached a certain age is inappropriate and dumb. I see a lot of young people that should have to take one every 6 months. The road would be a lot safer.
