**Abstract:**

For any integer $t \geq 1$, we say that a simple binary matroid is $I_t$-free if no rank-$t$ flats are independent. It is triangle-free if it has no circuit of size $3$. In this talk, we discuss a few problems regarding simple $I_t$-free, triangle-free binary matroids, with some partial results.
