Echis carinatus is mostly crepuscular and nocturnal, although there have been reports of activity during daylight hours.
During the daytime they hide in various locations, such as deep mammal burrows, rock fissures and fallen rotted logs.
In sandy environments, they may bury themselves leaving only the head exposed.
Often, they are most active after rains or on humid nights.
This species is often found climbing in bushes and shrubs, sometimes as much as 2 m above the ground.
When it rains, up to 80% of the adult population will climb into bushes and trees.
Once, it was observed that approximately 20 individuals had massed on top of a single cactus or small shrub.

Echis carinatus is one of the species responsible for causing the most snakebite cases due to their inconspicuous and extremely aggressive nature.

Its characteristic pose, a double coil with a figure of eight, with the head poised in the center, permits it to lash out like a released spring.

They move about mainly by sidewinding: a method at which they are considerably proficient and alarmingly quick.
They are also capable of other forms of locomotion, but sidewinding seems to be best suited to moving about in their usual sandy habitats.
It may also keep them from overheating too quickly, as there are only two points of contact with the hot surface in this form of locomotion.

In the northern parts of its range, these snakes hibernate in winter.
