True. But an observer sitting at the origin will not see it pass c,
and neither will any other observer moving in an intertial frame with
a relative velocity to the origin less than c. A spaceship
accelerating at constant acceleration (as measured by the crew) will
describe a hyperbolic path in a Loretnz diagram; it will never break
c.
