A straddle (the ATM straddle) involves ATM (or close) put and call. These options have usually the highest volume/liquidity, which generally leads to the lowest bid-ask spread. Check any option series and you should be able to see that bid-ask spread is tighter closer to ATM strikes. For instance check IWM and QQQQ, and you will be able to observe it.
