Access roads can be a mixed bag. Sometimes they're almost vacant, as most motorists will stick to the higher-speed roads they parallel. Others will be crowded because people want to be able to get to local destinations more easily than they can on the higher-speed limited access roads.

You'll have to take a look at the traffic in the area, and consider the width of the road in question, the quality of its pavement, and make your decision. One little tip - a mirror helps a lot as far as psychological comfort goes in a narrow road situation.
