In the paper a sufficient condition for all solutions of the differential equation with $p$-Laplacian to be proper. Examples of super-half-linear and sub-half-linear equations $(|y^{\prime }|^{p-1} y^{\prime })^{\prime } + r(t) |y|^\lambda \operatorname{sgn}y = 0$, $r>0$ are given for which singular solutions exist (for any $p>0$, $\lambda > 0$, $p\ne \lambda $).
