Q: What is a Primary Member? Additional Household Member? Associate Member? A:  As an Allstate Motor Club member, you can add additional members depending on which plan you have. Primary Member The primary member is the person whose name the membership is in. His or her name appears on the membership cards and receives all information about savings, plan information and billing Additional Household Member An additional member can be the primary member's spouse or one other adult driver in the household. This person is eligible to receive all benefits at no additional cost under our Platinum, Deluxe, Roadside Advantage, and RV Roadhelp plans. Under our Platinum, Deluxe and Roadside Advantage plans, 16 to 18 year old dependents are eligible to receive emergency roadside benefits only at no additional cost. Associate Member An associate member is another driver added to the membership beyond the first allowed additional household member. Associate members have the same benefits as the primary member. The primary member can add as many associate members (ages 16-23) to the plan as long as they live in the same household or are away at school. There is a nominal fee to add associate members.Go to  Membership Plans to see the cost for associate members under your plan.
