Dangerous and unprofessional driving in Fremont at 2:15 on 1/26/22. Tailgating, laying on the horn for no reason. By the looks of these other reviews, there is a documented problem with driver safety, a liability issue for this company.

If you come across one of this company's vans on the road in Sacramento, stay clear. Just had an encounter with a dark haired, bearded man driving a KM van who straddled two lanes to prevent cars from passing him, then laughed. Very discourteous driver all around as well. Hope someone sees this and speaks to him about how he's representing your company.

you should really train your drivers on how to navigate the highway seeing as how your company logo was all over the vehicles. If you're going to hold up the left lane not doing the speed limit you probably also shouldn't be brake checking people. Terrible image for the company and now a terrible review for the company.
