The origin of the weak insulating behavior of the resistivity, i.e.$\rho_{xx}\propto\ln(1/T)$, revealed when magnetic fields ($H$) suppresssuperconductivity in underdoped cuprates has been a longtime mystery.Surprisingly, the high-field behavior of the resistivity observed recently incharge- and spin-stripe-ordered La-214 cuprates suggests a metallic, as opposedto insulating, high-field normal state. Here we report the vanishing of theHall coefficient in this field-revealed normal state for all$T<(2-6)T_{\mathrm{c}}^{0}$, where $T_{\mathrm{c}}^{0}$ is the zero-fieldsuperconducting transition temperature. Our measurements demonstrate that thisis a robust fundamental property of the normal state of cuprates withintertwined orders, exhibited in the previously unexplored regime of $T$ and$H$. The behavior of the high-field Hall coefficient is fundamentally differentfrom that in other cuprates such as YBa$_2$Cu$_3$O$_{6+x}$ andYBa$_2$Cu$_4$O$_{8}$, and may imply an approximate particle-hole symmetry thatis unique to stripe-ordered cuprates. Our results highlight the important roleof the competing orders in determining the normal state of cuprates.
