In Lego Racers, the player assumes the role of either one of several pre-built Lego characters or a custom-built driver. The player can use virtual Lego, including pieces of Lego headwear, heads, bodies and legs, to construct characters, and can then build a custom car, using Lego bricks to build upon one of several designs of chassis.
In the circuit mode of Lego Racers, the player can race on one of seven "circuits", in which the player must gain the most points from among five competitors including one champion over the course of four races, each of which award the player points based on the order in which they finish in. Each circuit has a special driver, a "circuit champion", who performs better than the other computer-controlled racers. The seventh circuit comprises one track, where the circuit champion is Rocket Racer, the primary antagonist.
In the time race, the player races a single opponent, Veronica Voltage, who is the granddaughter of Professor Voltage, a character in the game Legoland. Veronica drives a ghost car that cannot crash into the player's car in any way. If the player wins races in every track of the first three circuits, they are awarded Veronica Voltage's car set.
A feature in the game allows the player to build cars of your design. At the beginning of the game, the player only has a limited array of bricks. As the player progresses through the game, more bricks of different circuits can be unlocked.
Veronica Voltage can be unlocked by beating her in all the time trial races.

- Fire any kind of red brick at the wall of two twin statues in front of the pyramid to open a door to the first secret passage.

LEGO Racers received mixed reactions from reviewers. The Microsoft Windows version received generally positive scores averaging at 75.45% according to GameRankings, based on 11 reviews. However the releases on both the PlayStation and Nintendo 64 received less positive reactions from critics despite featuring no gameplay differences. GameSpot gave the PC version 7.0 out of 10 describing the game as "a simple, colourful, and fun high-speed romp". However when they reviewed the Nintendo 64 version they scored it 4.5 out of 10 and said "With bland gameplay, boring racing and a frustrating Lego construction system, Lego Racers just translates into an incomplete package", while IGN said "The Nintendo 64 has seen many racing games, though none are quite like LEGO RACERS. The game, which is inspired by the building block toys, lets players build cars from one of 12 included sets of Legos" and gave it a 7.5 out of 10.
- One of the racers featured in this game is Baron von Baron. He later returned in LEGO Racers 2 and LEGO Island 2: The Brickster's Revenge, but was renamed "Sam Sinister" in those games.
