Roadside barrier including barrier sections coupled to one another, each having a horizontal portion, a vertical portion extending upward from the horizontal portion and a front plate coupled to the vertical portion and adapted to receive an impact from a vehicle. The vertical portion extends upward from a middle region of the horizontal portion to form a T-shaped structure. A vehicle impacting the front plate is situated on a front part of the horizontal portion thereby preventing the vehicle from tipping over. A mass, such as gravel or sand, is placed on a rear part of the horizontal portion, either loose or in a barrel or box. The barrier section is optionally designed to provide an increased drag once moved from its installation position, for example, by forming downwardly-extending protrusions on a lower surface of the horizontal portion which are adapted to penetrate the ground below the barrier section.
