Nothing against your grandmother but any govn't that renews a d/l for someone that old it should be mandatory that they take written and driving testing and only renew for ONE year.
This is one of my pet peeves ... the lack of regular testing upon renewals as well as how easy it is for people to get a lic. Testing should be much harder, include more "road sense" as well as motorcycle awareness. Then there's the issue of handing out a class 5 (a basic licence here in Canada) and then allowing the person to go jump into a huge single axle truck or motorhome or pull a travel trailer with absolutely NO experience .... yet you have to take special testing and get a special lic for a small, 2 wheeled vehicle.
aarrggghhhh!!!!
now let this dog lie and not get po-lit-i-cal
