Can I drive with B0028?
Yes, but drive carefully and get it checked soon. The airbag or seat belt system has a fault and may not protect you in a crash. The car still drives, but get it inspected soon.

B0028 stands for Right Side Airbag Deployment Control.
Symptoms you may notice

About this code
Code B0028 is frequently triggered when passengers slide the front seat back and forth, snagging the yellow airbag wiring harness underneath. The side airbag is disabled until repaired, leaving occupants unprotected against side-impact collisions.
