A woman is dead after a crash involving a fire truck and a car in Barton about 2pm on Monday.
It was unclear whether the fire truck was responding to an emergency and whether its lights and sirens had been activated. ACT Policing's detective acting station sergeant Marcus Boorman said this would form part of police's investigations.
The woman was the only person in the car. She was cut from the vehicle and treated at the scene by paramedics, before being taken to hospital where she later died.
"The driver of the vehicle that was struck by the fire truck sustained serious injuries and tragically has passed away at hospital later this afternoon," Mr Boorman said on Monday.
"Any serious collision is horrific and at the end of the day, we've got a job to do.
"Our thoughts go out to the family of the driver and also I'd like people to spare a thought for the emergency services personnel that are involved in these incidents."
Emergency services personnel who attended the scene would receive support through the relevant agencies, Mr Boorman said.
The incident happened at the intersection of Brisbane Avenue and Bowen Drive, close to the Australian Federal Police College. The intersection was closed for several hours after the crash, as were Wentworth Avenue and Macquarie Street in Barton.

The roads were cleared by about 8pm Monday, and traffic was allowed through.

"With any incident like this, we look at so many things," Mr Boorman said.
"We can map the scene, we look at speeds ... [we] speak to witnesses - so it's a long process, but it's so important that we do it right because we get one shot."
The Barton fatality is the fifth on ACT roads in 2019.
