Every ticket and accident you've had within 3 years is going to affect your rate, so there isn't much that can be done about that. Luckily, California
auto insurance rates are partially based on the number of miles you drive per year so you may want to re-evaluate the mileage listed on your policy and also when you shop around
. You might also consider a "physical damage only" policy (this type of policy doesn't include liability since the vehicle is being stored) while you're on deployment. This may not be available with every insurance carrier so you'll need to check around.
