My opinion is that if you have to train them to use a camera they are not exempt - that means they have no training or expertise in the field if you have to train them, thus, the exemption would not apply. So they would b non-exempt and you simply must pay them time and half for all hours worked over 40 per workweek. Colorado is one of the few states that not only requires employers to provide breaks, but also requires that employees be paid for some of this time. Colorado requires employers to offer both a meal break and paid rest breaks.
Under Colorado law, employers must give employees a 30-minute meal break once the employee has worked five hours. An employer does not have to pay for this time; in other words, meal breaks are unpaid. Covered employers include those in retail and service, food and beverage, commercial support service, dry cleaning and housekeeping, and health and medical industries. Some professions are specifically excluded from this requirement, including teachers and nurses.
If the nature of the job prevents employees from taking a break from all duties, employers may provide an on-duty meal period. However, this time must be paid.
Colorado also requires employers to provide rest breaks. (Covered employers are the same as for meal breaks.) Employers must allow employees to take a paid ten-minute rest break for every four hours (or major fraction) worked. If practical, these breaks must be provided in the middle of the work period.
The vehicle use policy is good as you have it.
