Depends on the bottler. Some are salary, some are hourly, some are union. Around here the bulk(grocery store delivery) drivers make the high 40's to low 50's, paid salary and are union. The sideload drivers(c-stores) have no cap, they are paid commision on top of a base pay plus case count.
Also, take into conderasion cost of living. My area has a low cost of living then you do in CA.
.........and if your woking for a local distributor hauling product $12-$13 (less as a new driver) and you will work some very long hours. I worked for a 7up distributor in the eighties.......I hated the summer with all the fairs, often I would not get done till 9PM at night and back to work at 7AM.
