fourth gear
Manual transmission setting
Fourth gear is the fourth-lowest gear ratio in a vehicle's transmission, typically used for highway cruising in conventional five- or six-speed systems.
Figuratively, to shift into fourth gear suggests moving to a higher level of effort or intensity, though fifth gear or high gear are more common for this metaphor.
