driver

A person who stays sober during a social gathering and is responsible for safely driving others from one location to another. Since Kara never drinks alcohol, she always offers to be the designated driver for her friends.

In control; in a dominant or influential position. With the new CEO in the driver's seat, the company has turned in its most profitable quarter in years.

In control of a situation; in a position of power. Primarily heard in UK. Make sure to get good grades now, so that you're in the driving seat when it comes time to choose a college. We're still leading in the polls, so nobody panic—we're in the driving seat here.

An aggravatingly slow driver. Likened to one out for a leisurely "Sunday drive." For the most part, I like the relaxed attitude down here. But I absolutely detest all the Sunday drivers on the road! It took me nearly an extra hour to get home because I got stuck behind some Sunday driver.

Fig. an annoying passenger who tells the driver how to drive; someone who tells others how to do things. I don't need any backseat driver on this project. Stop pestering me with all your advice. Nobody likes a backseat driver!

Fig. in control; in charge of things. (As if one were driving and controlling the vehicle.) Now that Fred is in the driver's seat, there is a lot less criticism about how things are being done. Joan can't wait to get into the driver's seat and do what she can to turn things around.

a slow and leisurely driver who appears to be sightseeing and enjoying the view, holding up traffic in the process. (Also a term of address.) I'm a Sunday driver, and I'm sorry. I just can't bear to go faster. Move over, you Sunday driver!

A passenger who gives unwanted and/or unneeded directions to the driver; also, a person who interferes in affairs without having knowledge, responsibility, or authority for doing so. For example, Aunt Mary drives us all crazy with her instructions; she's an incurable backseat driver. This term originated in the United States in the 1920s, when it was first used for a passenger legitimately directing a chauffeur, and it was quickly transferred to figurative use. Also see the synonym Monday-morning quarterback and the antonym take a back seat.

Also, in the saddle. In control, in a position of authority. For example, With the boss on vacation, Mr. Burns was in the driver's seat and enjoying it, or She waited until after the election, knowing that she'd be in the saddle then. The first expression dates from the 1800s, the second from the early 1600s. Also see at the helm.

COMMON If someone is in the driving seat, they have control of a situation. The radicals were in the driving seat, much to the anxiety of the moderates. Howe has warned against Britain not being in the driving seat as Europe takes important decisions. Those who had access to money were in the driver's seat.

A passenger who gives unasked-for and usually unwanted advice to the driver of a vehicle; by extension, anyone who interferes without having real responsibility or authority. The term originated in the United States during the 1920s, when many automobiles were chauffeur-driven and their passengers sat in the backseat, often quite legitimately telling the chauffeur where to go. Today the passenger’s location is irrelevant, the term being principally figurative. It has largely replaced the older armchair general. See also Monday-morning quarterback and the very different take a backseat.

In control. The analogy here is obvious, but the actual expression did not become common until the nineteenth century. Lord Beaverbrook is quoted (New Statesman, 1963) as saying of David Lloyd George, “He did not care in which direction the car was travelling, so long as he remained in the driver’s seat.” See also in the saddle.
