Narrative:
Maintenance truck; needed five minutes on runway xxl and was granted this access while holding short of runway xy on runway xxl. Meanwhile; aircraft X began taxiing to runway xxl while an inbound was about 10 miles out for runway xy. The south radar controller briefly called to coordinate something; but then hung up and this got the trainee and I in a brief discussion about what apreq [approval request] they may have been considering. We were using the correct memory aid to show that runway xxl was occupied and unavailable; however; our scan broke down and aircraft X was cleared for takeoff while taxiing on taxiway D towards D1; as the runway xy lander was already crossing the runway xy/ xxl intersection. Maintenance truck; then reported exiting runway xxl as he heard our clearance and saw the A320 turning from D1 to begin taking the runway. I quickly verified that maintenance truck had exited runway xxl; and he confirmed this immediately and then aircraft X continue lining up on runway xxl and he then commenced his takeoff roll. Training on local control was in progress and I was the OJT instructor.I could have refrained from discussing a theoretical apreq and maybe this would helped the trainee and I from having a degraded runway scan that is obviously much more important.

Title: Tower controllers reported a runway incursion with a departure and a vehicle.
Narrative: Maintenance truck; needed five minutes on Runway XXL and was granted this access while holding short of Runway XY on Runway XXL. Meanwhile; Aircraft X began taxiing to Runway XXL while an inbound was about 10 miles out for Runway XY.
