Postal Service vehicles should be used for one purpose only: official, authorized business.
Postal employees should not use a postal vehicle for any unauthorized personal uses, like commuting between work and home, running a personal errand or to do work for a second job.
Email email@example.com with any questions about use of a postal vehicle while on detail or postal travel.
Unauthorized use of postal vehicles violates the Standards of Ethical Conduct for Employees of the Executive Branch and federal law.
Penalties are steep and include mandatory suspension without pay for at least one month and further penalties where appropriate, up to and including removal from the Postal Service.
