In regards to social distancing requirements, what do we do when we have two employees attending a job site in one truck?

Carry out a risk assessment and see what can be implemented. For example, respiratory protection, face shields, or even taping a flexible piece of clear plastic between the front and rear seats (ensuring vision is not obstructed for driving) may help reduce the risk if it is not possible for employees to use separate vehicles. Ensure that work vehicles are thoroughly disinfected between shifts or use by different employees.
