Senior trooper

For some agencies, the insignia for this position consists of a gold colored 'ST' collar pin worn on the wearer's right lapel while others bear a 'senior trooper' plate that is located below their nametag.

Senior troopers take on the responsibility to use preventive measures in dealing with accidents and crime, enforce the law, conduct highway patrol, investigate, and perform related administrative duties in order to protect citizens, visitors, public highways, and property of the State or Commonwealth.

[1] Senior troopers are required to be knowledgeable on criminal and traffic laws, skilled in the use of firearms and operation of an issued vehicle.

Consideration for movement to senior trooper, master trooper, and senior special agent is based on years of experience, performance evaluation (determines eligibility and used in the event of a tie), discipline, weight control, and educational achievement (used only in the event of a tie).

In some agencies, becoming a senior trooper is not a rise in rank but does include a pay raise.
