去网上搜实时路况看是什么code, 参照下面的Code Requirement. 一定提前买个chain带着。 Requirement 1 (R-1): Chains are required on all vehicles except passenger vehicles and light-duty trucks under 6,000 pounds gross weight and equipped with snow tires on at least two drive wheels. Chains must be carried by vehicles using snow tires. All vehicles towing trailers must have chains on one drive axle. Trailers with brakes must have chains on at least one axle. Requirement 2 (R2): Chains or traction devices are required on all vehicles except four-wheel/all-wheel drive vehicles with snow-tread tires on all four wheels. NOTE: (Four-wheel/all-wheel drive vehicles must carry traction devices in chain control areas.) Requirement 3 (R3): Chains or traction devices are required on all vehicles, no exceptions.
一定得带着啊。
俺这里上山，雪大的时候，有刑警设路障检查，必须上了 snow chains 才可以继续往上开。很多没有准备好 snow chains 的都得 u turn 下山去买，沿路还有人高价兜售。
看你下周几去了，就现在看下周的预报来说，做好暴雪封山高速关闭的准备，或者是在高速里冻上十几个小时甚至过夜。---- 一个滑雪十年冬天每天必刷专业降雪天气预报的老鸟告诉你。
顺带说一句，美国好心人真多！
1992年前我差点在那里送命！
打算下周三去 请教大神那天怎么样啊 带着娃封路的话伤不起啊 啥时候去天气能稳定一些呢 以前去滑雪（不是tahoe）从来没遇见过下雪 更别说封路

需要，而且要上4条雪链。4轮驱动在雪地更容易失控。不要以为越野车适合雪地。越野车是脱困能力更好，但是转弯时更容易失控
谢谢回复 那怎么那人不让我们上 直接让我们走了🤨 奇怪
看啥level. Level 1 4wd 不需要。level 3都需要。昨天做的research. 原来啥都不懂。
判断要不要装雪链的标准是：四驱加all weather tires。最最低的标准是四驱。
长期的天气预报不会那么准确，只能是看个趋势，等到周末再看预报可能就比较明朗了。现在只能说周三的下雪堵车的风险挺大
