We consider one space dimension scalar conservation law with strict convex flux. The problem is to study exact controllability of entropy solutions. Some partial results have been obtained in [17] and we investigate the precise condi- tions under which exact controllability problem admits a solution. The basic ingredients in the proof of these results are [14], Lax-Oleinik [12] explicit for- mula and finer properties of generalized characteristics introduced by Dafermos [11].
